Village agriculture is very important in Bangladesh. In emerging nations like our own, agriculture has a significant impact on national GDP. Basically, because of our current circumstances, the monsoons, which are agriculture's primary source of water, are insufficient. The irrigation system is used in agriculture as a solution to this issue. In this technique, the agricultural field will receive water depending on the type of soil. In agriculture, there are two factors to consider: the soil's moisture content and its fertility. There are already a variety of irrigation options available to lessen the demand for rain. An electrical power on/off schedule controls this kind of method. The use of IOT to create a smart irrigation system is covered in this article. Our method uses hydropumps to regulate multiple pumps at once, which saves time and energy. This system will have a significant impact on the national economy if we implement it.
Automated irrigation system based on soil moisture using arduino boardjournalBEEI
In recent years, the best system of irrigation is studied by reducing the wasted amount of water and electricity. Automatic irrigation is the use of a device to operate irrigation structures so the change of flow of water from one bay, or set of bays, to another can occur in the absence of the irrigator. In this work, automatic control system of solar irrigation implemented practically using Arduino board. This photovoltaic (PV) system is applied in the garden of Engineering Technical College- Mosul (city in Iraq). PV system can be adjusted by many regions in Iraq where it planned to connect on small part of land. Irrigation process is controlled depending on moisture sensor that connected to sense the soil moisture and giving data to Arduino read pin. According to the program that uploaded to Arduino, DC pump can be controlled as ON-state or OFF-state as respect to the soil moisture percentage ratio. Finally, the practical results are approximately similar to that obtained from proteus Arduino simulator.

Modern digitalized era of our 21st century needs automation in each and every sector. Combining technology to increase the credibility of an another technology is not at all a very good idea. India is a country where agriculture is the main and vast field for our national financial system. So we have tried to implement the fruitfulness of technology to combine with agricultural field so that the growth of crops can increase exponentially. Irrigation is the methodology of misleadingly supplying water to land where harvests are developed. Generally hand pumps, channel water and precipitation were a significant wellspring of water supply for watering system. This strategy has prompted serious disadvantages like under watering system, over-watering system which thus causes filtering and loss of supplement substance of soil. Changing ecological conditions and lack of water have prompted the requirement for a framework which effectively oversees watering system of fields. Computerized watering system framework is a machine based framework, which robotizes the watering system of area by joining different programming and equipment approaches together for field watering system.
This paper manages a definite study of different GSM based mechanized ranch watering system frameworks. GSM serves as an essential part since it is in charge of controlling the watering system office and sends them to recipient through coded sign. Our study is focused on examination of different GSM approach.
The aim of our project is to minimize this manual intervention by the farmer. Automated Irrigation system will serve the following purposes: 1) As there is no un-planned usage of water, a lot of water is saved from being wasted. 2) The irrigation is the only when there is not enough moisture in the soil and the sensors decides when should the pump be turned on/off, saves a lot time for the farmers. This also gives much needed rest to the farmers, as they don’t have to go and turn the pump on/off manually.

For the agriculture sector, detecting and identifying plant diseases at an early stage is extremely important and
still very challenging. Machine learning is an application of AI that helps us achieve this purpose effectively. It
uses a group of algorithms to analyze and interpret data, learn from it, and using it, smart decisions can be
made. For accomplishing this project, a dataset that contains a set of healthy & diseased plant leaf images are
used then using image processing we extract the features of the image. Then we model this dataset with
different machine learning algorithms like Random Forest, Support Vector Machine, Naïve Bayes etc. The aim is
to hold out a comparative study to spot which of those algorithm can predict diseases with the at most
accuracy. We compare factors like precision, accuracy, error rates as well as prediction time of different
machine learning algorithms. After all these comparison, valuable conclusions can be made for this project.
Due to diagnosis problem in detecting lung Cancer, it becomes the most dangerous cancer seen in human being. Because of early diagnosis, the survival rate among people is increased. The prediction of lung cancer is the most challenging cancer problem, due to its structure of cells in human body. In which most of tissues or cells are overlapping on one another. Now-a-days, the use of images processing techniques is increased in growing medical field for its disease diagnosis, where the time factor plays important role. Detecting cancer within a time, increases the survival rate of patients. Many radiologists still use MRI only for assessment of superior sulcus tumors and in cases where invasion of spinal cord canal is suspected. MRI can detect and stage lung cancer and this method would be excellent of lung malignancies and other diseases.

As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.
Natural resources are vanishing universal while at the similar time the generated wastes from the industry are
growing substantially. The sustainable development for construction requires the use of nonconventional and
innovative materials, and recycling of demolished and waste materials so to compensate the lack of natural
resources and to find alternative ways of conserving the environment. So, this paper presents the consequences
of an experimental study carried out to evaluate the power-driven properties of concrete mixtures in which fine
aggregate (sand) was swapped with Copper Slag (CS) while coarse aggregates were swapped by used and
recycled concrete coarse aggregate (RCA) from demolished structure or building. Both the coarse and fine
aggregate were replaced with percentages 0% (for the control mixture), 10%, 20%, 30%, of Copper Slag by
weight ratio. Tests were performed for properties of new concrete and toughened Concrete simultaneously.
Slump test was conducted to regulate the workability of the several design concrete mix. Compressive strength
and split tensile strength were determined at 7, 28 days of curing completely.
The results show that workability shrinkages slightly with rise in Copper Slag ratio, however workability for
the illustrations were within the prearranged boundary for M25 concrete. Test results shown substantial
enhancement in the strength assets of simple concrete by the insertion of CS alone whereas a reverse tendency
in observed for growing proportion of RCA in the illustration. The result of this study work displayed that
Copper slag in addition recycled concrete aggregate can be efficiently used in physical concrete as a standby of
coarse aggregate and fine aggregate (sand) respectively.
The world of manufacturing world is broadly classified into two main categories such as cold working and hot
working process. The process in the manufacturing world which is conducted above the recrystallization
temperature are called as hot working process while the process which is conducted below the recrystallization
temperature of the work piece is called cold working process.in the above categorization, the casting and
forging process is considered as the hot working process while other processes were kept under cold working
process category. The process for our review is forging and in our research paper, we are focusing on the
forging process, the types of forging process and the various parameters that are considered as a tool for the
process optimization of the forging.
As catastrophic bridge collapse accidents not only cause significant loss of property, but also have a severe social impact. Therefore, the structural health monitoring of bridges for damage detection by vibration analysis gets more attention. Reinforced concrete bridges are the most common and extended structures present in the worldwide. These structures are often characterized by Piers, Abutments, deck slabs. This paper looks on the work of modelling and analysis of bridge in STAAD.Pro software, and the specific bridge model is taken of a particular span. It is subjected to vary Young’s modulus (E) in the mid span of bridge deck slab to induce damage in order to obtain maximum bending moment, as the structural strength reduces. From the analysis Mu/bd2 values from SP 16 code is used to identify the damage on the bridge deck slab, then natural frequency of the bridge, mode shapes, variation of the deflection and node displacements of bridge deck slab under the action of static and dynamic load at different aspect ratios with original design parameters and at failure is carried out in this project.
The power supply system is completely hooked into three major parts. First one is generation, second one is
transmission and the last one is distribution of electricity supply at the range of 415V to 400V approx. But while
the fault occurs it affects other lines additionally, and this causes difficulties for local people and additionally
perturb the flow of current in different areas. This eccentric and perturbed supply of nuisance is very
hazardous as it cannot be ceased when it comes to equal distribution of electricity. The area suffering from
faults and the other both get affected. So to stop all these we have implemented this project of Coordination of
over current relay utilising optimisation technique. We have utilised crow search algorithms with Kennedy as
swarm perspicacity algorithms which are very auxiliary in storing excess electricity supply and can be used
when needed. With the avail of this we can renovate the potency supply and this will conclusively implement
our main objective of this project.
The classification of different types of tumors is of great importance in cancer diagnosis and its drug discovery. Cancer classification via gene expression data is known to contain the keys for solving the fundamental problems relating to the diagnosis of cancer. The recent advent of DNA microarray technology has made rapid monitoring of thousands of gene expressions possible. With this large quantity of gene expression data, scientists have started to explore the opportunities of classification of cancer using a gene expression dataset. To gain a profound understanding of the classification of cancer, it is necessary to take a closer look at the problem, the proposed solutions, and the related issues altogether. In this research thesis, I present a new way for Leukemia classification using the latest AI technique of Deep learning using Google TensorFlow on gene expression data.

performance of professors at all levels. COVID-19 stressors have put more impact on Assistant Professors,
Associate Professors and Professors performance than the organizational stressors in this study. Research and
publication seems to be the common stress for professors at all levels. Loss of family members due to pandemic
and reduction of salary are the common contributors of stress under COVID-19.
Softmax function is an integral part of object detection frameworks based on most deep or shallow neural
networks. While the configuration of different operation layers in a neural network can be quite different,
softmax operation is fixed. With the recent advances in object detection approaches, especially with the
introduction of highly accurate convolutional neural networks, researchers and developers have suggested
different hardware architectures to speed up the overall operation of these compute-intensive algorithms.
Xilinx, one of the leading FPGA vendors, has recently introduced a deep neural network development kit for
exactly this purpose. However, due to the complex nature of softmax arithmetic hardware involving
exponential function, this functionality is only available for bigger devices. For smaller devices, this operation is
bound to be implemented in software. In this paper, a light-weight hardware implementation of this function
has been proposed which does not require too many logic resources when implemented on an FPGA device.
The proposed design is based on the analysis of the statistical properties of a custom convolutional neural
network when used for classification on a standard dataset i.e. CIFAR-10. Specifically, instead of using a brute
force approach to design a generic full precision arithmetic circuit for SoftMax function using real numbers, an
approximate integer-only design has been suggested for the limited range of operands encountered in realworld
scenario. The approximate circuit uses fewer logic resources since it involves computing only a few
iterations of the series expansion of exponential function. However, despite using fewer iterations, the function
has been shown to work as good as the full precision circuit for classification and leads to only minimal error
being introduced in the associated probabilities. The circuit has been synthesized using Hardware Description
Language (HDL) Coder and Vision HDL toolboxes in Simulink® by Mathworks® which provide higher level
abstraction of image processing and machine learning algorithms for quick deployment on a variety of target
hardware. The final design has been implemented on a Xilinx FPGA development board i.e. Zedboard which
contains the necessary hardware components such as USB, Ethernet and HDMI interfaces etc. to implement a
fully working system capable of processing a machine learning application in real-time.
Composite materials are becoming popular in various industries such as aerospace industry, automotive industry, and wind energy. We have seen global surge in the demand of composites particularly carbon fiber reinforced plastic (CFRP) composites, which has led to huge volume of manufacturing and end-of-life waste material. The most common way for disposing of composite waste is through landfills. However, current, and impending legislations such as Directive on Landfill of Waste, have limited the amount of composite waste permitted for landfilling. Also, for making of pristine carbon fiber requires high amount of energy if we compare it to other materials like steel and aluminium. This generates a need to find out a way to recycle and reuse the waste material or the end-of-life material in different sector applications. This study mainly focuses on the strength comparison of pristine(virgin) CFRP with recycled CFRP and conducting finite element analysis on some parts made from virgin and recycled material. Also, details about mechanical recycling, cost estimation for producing virgin material as well as for recycling the material must be taken into account.
Flood is the most devastating environmental hazard throughout the world causing loss of precious human lives
and damage to infrastructure. They occur by unusual overflow of water over the banks of rivers or channels
thus inundating the surrounding area. The magnitude and intensity of floods depends on hydrological and
physical characteristics of the catchment and river channel. Adverse effects of these floods can be alleviated
through mapping of floodplain which is essentially the area around the channel which is likely to be flooded.
One of the methods of floodplain delineation is modeling the river flow using computer models such as the
Hydrologic Engineering Center River Analysis System (HEC-RAS). In this study the application of 2D HEC-RAS
river model is used to develop a floodplain map of river Kabul.
Alur Ilmu is a concrete-cement drainage canal built since the construction of the Universiti Kebangsaan
Malaysia in 1970s for rain, storm, and groundwater; flowing towards the main discharge point that joins the
Langat River Selangor. In this study, water quality parameters (i.e. DO, BOD, COD, Ammoniacal Nitrogen, TSS,
pH) and heavy metal (i.e. Zinc, Cadmium, Copper, Plumbum, Manganese, Ferum, Chromium, Nickel) were
assessed along the Alur Ilmu canal at five stations from upstream to downstream and compared with Malaysian
Water Quality Index. Overall, all the research stations were in Class III (slightly polluted), and there were
highly significant differences for all the water quality parameters (p <0.001) across five stations except for BOD,
COD and TSS. The concentration means of heavy metals analyzed were below the recommendation of Standard
for Water and Packaged Drinking Water (Food Act 1985) for Malaysia except for Fe (>0.30 mg/L) and Mn
(>0.001 mg/L). However, the mean concentration of Fe and Mn in Alur Ilmu were still acceptable by USEPA; Mn
(<0.50 mg/L) and Fe (<1.0 mg/L). In conclusion, this study gives a baseline toward future better conservation
and management of Alur Ilmu as it has potential as cultural identity and recreational uses in UKM.
The compressive strength, flexural strength, and split tensile strength of Reactive Powder concrete are all
investigated in this study (RPC). The lack of ductility in ordinary concrete is considered a key concern in this
research. RPC is being explored as a solution for the aforementioned challenge as the building industry's
technology advances. Cement, sand, water, admixture, and superplasticizer are all included in the RPC. The
reactive powder concrete mixture is made by changing the percentages of super plasticizer (2%, 3% and 4%),
silica fumes (10%, 20%, and 30%), while maintaining the dose of quartz powder constant. At the outset of this
study, compressive strength, flexural strength, and split tensile strength targets of 140-160Mpa, 20-30Mpa, and
15-20Mpa were set. However, due to a change in material qualities that were locally accessible and of low
quality, the results produced after the investigation were unsatisfactory to get the findings, the RPC was mixed,
cast, cured, and tested in the concrete laboratory using three different mix proportions.
150mmX150mmX150mm cube, 500mmX100mmX100mm beam, and 150mm diameter and 300mm height
cylinder are all made of fresh concrete. The casted RPC is then cured in a water tank at room temperature for 7,
14, and 28 days before being oven dried for 24 hours at 60 degrees Celsius. The final results were documented
and discussed, as well as conclusions and recommendations based on the findings.
The main purpose of this project is to create a face recognition-based group action observance system for
establishment to boost and upgrade the present group action system into additional economical and
effective as compared to before. the present recent system encompasses a heap of equivocation that
caused imprecise and inefficient of group action taking several issues arise once the authority is unable
to enforce the regulation that exist within the recent system. The technology operating behind are the
face recognition system. The external body part is one of the natural traits which will unambiguously
determine a personal. Therefore, it's accustomed track down specification because the possibilities for a
face to diverge is low. Face data collections are created to pump information into the recognizer formula.
Then, throughout the group action taking session, faces are compared against the information to hunt for
identity. Once a personal is known, its group action is taken down automatically saving necessary data
into a stand out sheet.

ABSTRACT
Village agriculture is very important in Bangladesh. In emerging nations like our own, agriculture has a
significant impact on national GDP. Basically, because of our current circumstances, the monsoons, which are
agriculture's primary source of water, are insufficient. The irrigation system is used in agriculture as a solution
to this issue. In this technique, the agricultural field will receive water depending on the type of soil. In
agriculture, there are two factors to consider: the soil's moisture content and its fertility. There are already a
variety of irrigation options available to lessen the demand for rain. An electrical power on/off schedule
controls this kind of method. The use of IOT to create a smart irrigation system is covered in this article. Our
method uses hydropumps to regulate multiple pumps at once, which saves time and energy. This system will
have a significant impact on the national economy if we implement it.
I. INTRODUCTION
Sensors are crucial parts of numerous applications, including those that monitor traffic flow, weather
conditions, building safety and security, and many others. They are also used in many different sectors for
process control. For example, it is necessary to measure the temperature, humidity, and pressure when
monitoring the weather. As a result, sensors have always been charged with performing this role. Climate and
weather have a significant impact on human life. It is known that six factors, including ambient temperature,
radiation, air flow, humidity, activity level, and clothing thermal resistance, have a significant impact on a
person's ability to maintain a comfortable body temperature (ISO 7730, 1984; Bu et al., 1995). These
inexpensive, dependable electronic sensors are now better able to monitor environmental conditions thanks to
technological advancements.
Using sensors for indoor climate and environment, Kang and Park (2000) and Odlyha et al. (2000) have created
monitoring systems based on the aforementioned factors. Monitoring temperature and relative humidity has
proven to be more effective when these sensors are combined with a data gathering system (Moghavvemi et al.,
2005). Using capacitive-based sensors, Ong et al. (2001) and Defenses and Wise (2005) proposed wireless
sensing microsystems for environmental monitoring. Surface acoustic waves (SAW) devices were first used as
pressure sensors in 1994 by Buff et al. and as temperature sensors in 1993 by Vlassov et al. However, because
some of these systems include fabrication procedures and the usage of on-chip transmitter circuits, they are
highly expensive and complicated in nature. Our goal is to develop an automatic irrigation system and irrigation
database that will be a smart tool for farmers. Using this method, we can also check the quality of the soil and
the weather. We can state "Our country will generate more harvest every year" so easily.
Background & Problem Statement
In today's information and technology-driven world, weather monitoring and forecasting are crucial for
planning human activities. For example, planning human activities in agriculture, where and when to plant and
wait for harvest, in our social lives, where and when to hold events, and in transportation, how safe it is to
travel by land, air, or water, all depend on weather, whether it's a help or a hindrance. With the use of sensors
and telecommunication, it is now possible to monitor and analyze weather conditions without requiring the
user to exert much effort or human interaction. Certain weather situations can be identified or anticipated
using weather monitoring systems before they actually occur. However, wire weather monitoring systems
enable users to view these systems online or remotely without having to be present physically. In contrast to

weather forecasting, the system uses weather sensors to sense the climatic conditions and analyzes the
patterns to provide a more precise prediction. Data is sensed across a predetermined distance by wire, and the
results are shown on an LCD panel. It can identify a number of meteorological factors, including temperature,
humidity, wind speed, and wind direction. By integrating the numerous sensors on the microcontroller, it is
possible for one weather monitoring station to perceive a variety of weather situations, which lowers the cost
of building a weather monitoring station that can only evaluate a specific kind of weather condition. Farmers
may benefit from the quick growth of more crops thanks to automatic watering.
Farmers in the current system must go a considerable distance to turn on the hydro pump, which costs them a
lot of time. Farmers occasionally fail to turn off their motors in time, wasting a lot of water and electricity. Thus,
they must pay an additional electric charge. Our system has the capability to resolve this issue.
Aim
The goal of this project is to develop an automatic irrigation system using IOT that can: Gather information
from many sources, including information on soil moisture, temperature, and weather. If the data is low on
moisture, an LCD will show the moisture level and pump status. Also, it sent information to our database. Our
apps will receive a trigger from the database, allowing us to quickly see the condition of the pump.
II. METHODOLOGY
Wire with weather conditions observing framework considers weather patterns to be precisely anticipated to
take into consideration legitimate preparation of occasions or exercises which depend on climate as a central
point. It is basically better compared to a weather conditions estimating framework which includes broad
investigation, computations and picking the right weather conditions figure models that best foresee the
climate. 4 Weather conditions estimating frameworks are typically untrustworthy because of the time contrast
between when the weather conditions is really anticipated and when it comes into stage. The utilization of a
wire with weather conditions observing framework kills the issues of people collaborating straightforwardly
with the frameworks, or doing all the significant work in foreseeing the climate. Escalated information
investigation, handling and computations are finished by the framework all things considered, consequently,
eliminating the issues of human blunders and giving an easy to understand framework that permits clients with
little abilities of working a specialized gadget, the valuable chance to work the checking framework. The
weather conditions observing framework can detect different weather patterns and permits the client to get
data about weather patterns through LCD Show, permitting the client to have fractional control of the
framework without being in a similar area as the framework. In situations where a weather conditions
estimating framework will foresee precipitation in the entire of a city or city, though, it downpours in just a
specific level of the area, adds to the lack of quality of the framework .The weather conditions checking
framework will, nonetheless, foresee the climate, covering a more modest distance which will give better
precise outcomes. They can fill in as an open air unit to detect ecological weather patterns or as an indoor unit
to give data about the genuine feel of the climate or temperature feel of gear. The Weather Pack weather station
monitoring system. The Weather Rack weather sensors (anemometer and wind vane) acquired were designed
to measure wind speed and wind direction.
Arduino Nano
Arduino Nano is a microcontroller board based on the ATmega328. It contains everything needed to support
the microcontroller. The software was customized for the function of the weather station monitoring wind
speed and wind direction.
Node MCU
Basically, NodeMCU is Lua Interpreter, so it can understand Lua script easily. When we write Lua scripts for
NodeMCU and send/upload it to NodeMCU, then they will get executed sequentially. It will not build a binary
firmware file of code for NodeMCU to write. It will send the Lua script as it is to NodeMCU to get executed.
In Arduino IDE when we write and compile code, the ESP8266 toolchain in the background creates a binary
firmware file of the code we wrote. And when we upload it to NodeMCU then it will flash all NodeMCU firmware
with newly generated binary firmware code. In fact, it writes the complete firmware. That’s the reason why
NodeMCU does not accept further Lua scripts/code after it is getting flashed by Arduino IDE. After getting

flashed by Arduino sketch/code it will be no more Lua interpreter and we get errors if we try to upload Lua
scripts. To start again with Lua script, we need to flash it with NodeMCU firmware.
Selection of Sensors
The parameters measure Wind speed and Wind direction. The following sensors were used for each parameter:
1. Soil Moisture – Fore getting water info is soil
Positioning the sensor
Figure 1 shows the proper placement of the Soil Moisture Sensor. The prongs should be oriented horizontally,
but rotated onto their side, like a knife poised to cut food, so that water does not pool on the flat surface of the
prongs.
The horizontal orientation of the sensor ensures the measurement is made at a particular soil depth. The entire
sensor can be placed vertically, but because soil moisture often varies by depth, this is not usually the desired
orientation. To position the sensor, use a thin implement such as a trenching shovel to make the pilot hole in
the soil. Place the sensor into the hole, making sure the entire length of the sensor is covered. Press down on
the soil along either side of the sensor with your fingers. Continue to compact the soil around the sensor by
pressing down on the soil with your fingers until you have made at least five passes along the sensor. This step
is important, as the soil adjacent to the sensor surface has the strongest influence on the sensor readings.
Removing the Sensor
When removing the sensor from the soil, do not pull it out of the soil by the cable. Doing so may break internal
connections and make the sensor unusable.
Volumetric Water Content
In very simplified terms, dry soil is made up of solid material and air pockets, called pore spaces. A typical
volumetric ratio would be 55% solid material and 45% pore space. As water is added to the soil, the pore
spaces begin to fill with water. Soil that seems damp to the touch might now have 55% minerals, 35% pore
space and 10% water. This would be an example of 10% volumetric water content. The maximum water
content in this scenario is 45% because at that value, all the available pore space has been filled with water.
This soil is referred to as being saturated, because at 45% volumetric water content, the soil can hold no more
water.

Optional Calibration Procedure
It is not usually necessary to perform a new calibration when using the Soil Moisture Sensor. The Soil Moisture
Sensor has a stored calibration that will give good results. If, however, very accurate readings are needed, a
calibration using the sample soil type to be measured is recommended. Two methods are described below.
Method 1 is faster and easier, but potentially less accurate than Method 2.
Calibration Method 1: Two-Point Calibration
This is the faster and easier of the two methods, but is potentially less accurate.
1. Dry the soil in a drying oven at 105˚C for 24 hours.
2. Obtain a water-tight container that is large enough to fully insert the sensor with room for at least 2 cm on
all sides. A plastic shoe box or similar works well.
3. When cool, break up any large clods until all soil fits through a 5 mm screen.
4. Connect the Soil Moisture Sensor to the interface and start the data-collection program.
5. Pour the soil into the container and position the sensor as shown. The prongs should be oriented
horizontally, but rotated onto their side–like a knife poised to cut food–so that water does not pool on the
flat surface of the prongs.
6. Press down on the soil along either side of the sensor with your fingers. Continue to compact the soil around
the sensor by pressing down on the soil with your fingers until you have made five passes along the sensor.
7. Add more soil on top of the compacted soil so that the sensor is buried at least 3 cm below the soil surface.
8. Compact the soil again using a clenched fist.
9. Enter the calibration routine of your program. Keep this first calibration point and assign a value of 0. This
represents 0% volumetric water content.
10.Remove the sensor from the soil.
11.Determine the approximate volume of soil used. This can be done by packing it into a large, graduated
beaker.
12.Return the soil to the calibration container.
13.Obtain a volume of distilled water that equals 45% of the volume of the soil. If, for example, you used 3500
mL of soil, you would obtain 1575 mL of distilled water.
14.Add the distilled water to the soil and mix well.

15.Position the sensor in the wet soil, again making sure the sensor is completely covered and that there are no
gaps between the soil and the sensor.
16.Keep this second calibration point, assigning it a value of 45. This represents 45% volumetric water content.
17.Your sensor is now calibrated for this soil type. If you are using Logger Pro 3, you can save the calibration
directly on the sensor. If not, you may want to record the calibration values for future use.
Calibration Method 2: Multiple-Point Calibration
This method is more accurate, but requires more time and effort than Method 1.
1. Obtain and number 12 drying jars. The jars must be able to withstand the 105°C temperature of the drying
oven.
2. Weigh and record the mass of each jar.
3. Prepare the dry soil by breaking up large clods until all soil fits through a 5 mm screen. Note: The soil
should be fairly dry, but does not need to be oven-dry for this method.
4. Obtain a water-tight container that is large enough to fully insert the sensor with room for at least 2 cm on
all sides. A plastic shoe box or similar works well.
5. Connect the Soil Moisture Sensor to the interface and start the data-collection program.
6. Pour the soil into the container position of the sensor as shown. The prongs should be oriented horizontally,
but rotated onto their side–like a knife poised to cut food– so that water does not pool on the flat surface of
the prongs.
7. Press down on the soil along either side of the sensor with your fingers. Continue to compact the soil around
the sensor by pressing down on the soil with your fingers until you have made five passes along the sensor.
8. Add more soil on top of the compacted soil so that the sensor is buried at least 3 cm below the soil surface.
9. Compact the soil again using a cleched fist.
10.Enter the calibration portion of the data-collection program and record the voltage reading from the
sensor. Note: In this method, entering the calibration portion of the program is used only to obtain a raw
voltage reading from the sensor. You will not be completing a typical 2-point calibration in the software.
11.Use a soil core tool to take three volumetric soil samples adjacent to the sensor.
a. Insert the sampling cylinder fully into the soil.
b. Remove the soil core.
c. Dispense the core into a drying jar.
d. Weigh and record the mass of the jar plus soil.
e. Repeat Steps a–d for two additional core samples.
12.Remove the sensor from the soil.
13.Decide on a standard volume of distilled water that will increase the water content by 3 to 10% for each
measurement. If you are unsure about the amount of water to add, measure the volume of soil you are using.
Use a volume of distilled water equal to 5% of the volume of the soil.
14.Add one aliquot of distilled water to the soil in the amount decided upon in Step 13. To avoid clumping, add
the water in small amounts, mixing thoroughly.
15.Replace the sensor in the soil. Press down on the soil along either side of the sensor with your fingers.
Continue to compact the soil around the sensor by pressing down on the soil with your fingers until you
have made five passes along the sensor.
16.Add more soil on top of the compacted soil so that the sensor is buried at least
17.Compact the soil again using a clenched fist.

18.Record the voltage reading from the sensor.
19.Repeat Steps 11–18 two more times for a total of four levels of water content.
20.Dry and weigh the 12 soil samples to determine gravimetric water content.
a. Place the jars in a drying oven for 24 hours at 105˚C.
b. Allow the samples to cool until the soil temperature is near ambient.
c. After cooling, weigh the soil samples again to determine dry weight.
21.Determine the volumetric water content, θ, for each of the four samples.
22.Calculate the gravimetric water content, w.
where m is the mass and the subscripts w and m refer to water and minerals.
b. Calculate the bulk density, ρb.
where Vt is the total volume of the sample.
c. Calculate the volumetric water content.
The density of water, ρw, is 1 g/cm3.
Example
Soil sampling volume (Vt) 16.1 cm3
Soil sample initial weight (with jar) 84.065 g
Dried sample weight (with jar) 81.113 g
Jar weight (tare) 57.894 g
Mass of water (initial–dry weight) (mw) 2.952 g
Mass of dry soil (dry–tare weight) (mm) 23.219 g
22.Construct a calibration curve by graphing volumetric water content vs. the corresponding sensor output
voltage at that water content. There is an experiment file in Logger Pro (version 3.4.5 or newer) set up for
this purpose. It is named “Soil Moisture Calibration,” and can be found in the Soil Moisture Sensor folder in
the Probes & Sensors folder. Alternatively, you can open a new file in Logger Pro with no sensors connected
and type the values into the data table.
23.Perform a linear regression on the calibration curve and record the slope and intercept.
24.Connect the sensor and start your data-collection program.
25.Proceed to the calibration portion of the program and manually enter the values for slope and intercept.
26.Your sensor is now calibrated for this soil type. If you are using Logger Pro 3, you can save the calibration
directly on the sensor. If using LabQuest or a calculator, you may want to record the calibration values for
future use.

III. THEORETICAL MODEL
To improve human lives, telecommunication technologies are expanding and adding more innovative functions.
An ARDUINO NANO will be used in this project.
Defining of ARDUINO
An Arduino is actually a microcontroller based kit which can be either used directly by purchasing from the
vendor or can be made at home using the components, owing to its open source hardware feature. It is basically
used in communications and in controlling or operating many devices. It was founded by Massimo Baozi and
David Cuatrilloes in 2005
Arduino’s processor basically uses the Harvard architecture where the program code and program data have
separate memory. It consists of two memories- Program memory and the data memory. The code is stored in
the flash program memory, whereas the data is stored in the data memory. The Atmega328 has 32 KB of flash
memory for storing code (of which 0.5 KB is used for the bootloader), 2 KB of SRAM and 1 KB of EEPROM and
operates with a clock speed of 16MHz.

Analog inputs: It has 6 analog input/output pins, each providing a resolution of 10 bits.
A Ref: It provides reference to the analog inputs
Reset: It resets the microcontroller when low.
Program an Arduino
The most important advantage with Arduino is the programs can be directly loaded to the device without
requiring any hardware programmer to burn the program.
This is done because of the presence of the 0.5KB of Boot loader which allows the program to be burned into
the circuit. All we have to do is to download the Arduino software and write the code.
The Arduino tool window consists of the toolbar with the buttons like verify, upload, new, open, save, serial
monitor. It also consists of a text editor to write the code, a message area which displays the feedback like
showing the errors, the text console which displays the output and a series of menus like the File, Edit, Tools
5 Steps to program an Arduino
● Programs written in Arduino are known as sketches. A basic sketch consists of 3 parts
1. Declaration of Variables
2. Initialization: It is written in the setup () function.
3. Control code: It is written in the loop () function.
● The sketch is saved with Ino extension. Any operations like verifying, opening a sketch, saving a sketch can
be done using the buttons on the toolbar or using the tool menu.
● The sketch should be stored in the sketchbook directory.
● Chose the proper board from the tools menu and the serial port numbers.
● Click on the upload button or chose upload from the tools menu. Thus the code is uploaded by the boot
loader onto the microcontroller.
Few of basic Arduino functions are:
● digital Read(pin): Reads the digital value at the given pin.
● digital Write (pin, value): Writes the digital value to the given pin.
● pin Mode (pin, mode): Sets the pin to input or output mode.
● analog Read(pin): Reads and returns the value.

IV. HARDWARE DEVELOPMENT
The reader will learn about the system's building blocks in this chapter as well as how the hardware
components are integrated. It explains how the LCD is connected and how the sensors are interfaced with the
microcontroller on the Arduino board.
Components
● ARDUINO(NANO)
● Center Tapped Transformer
● Resistor
● Variable Resistor
● Capacitor
● Diode
● Voltage Regulator

● LCD
● Transistor

● Soil Moisture Sensor
● Varo Board

Center-tapped Transformer
The operation and theory behind a Center tapped transformer is very similar to a normal secondary
transformer. A primary voltage will be induced in the primary coil (I1and I3) and due to magnetic induction the
voltage will be transferred to the secondary coil. Here in the secondary coil of a center-tapped transformer,
there will be an additional wire (T2) which will be placed exactly at the center of the secondary coil, hence the
voltage here will always be zero.
If we combine this zero potential wire (T2) with either T1 or T2, we will get a voltage of 12V AC. If this wire is
ignored and voltage across T1 and T2 is considered then we will get a voltage of 24V AC. This feature is very
useful for the function of a full wave rectifier. Let us consider the voltage given by the first half of the secondary
coil as Va and the voltage across the second half of the secondary coil as Vb as shown in the diagram below
As we know the voltage across the coil depends on the number of turns on the primary and secondary coil.
Using the turns ratio formula, we can calculate the secondary voltage as:
Va= (
Na
Nb
)*Vp
Vb= (
Na
Nb
) ∗ Vp

Resistor
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic
circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.
Figure: Resistor
Variable Resistor
A resistor restricts current flow in an electrical circuit without switching the current off. A variable resistor
allows more control over current flow by changing the amount of resistance. When resistance increases in a
variable resistor, the amount of current that is allowed to flow in a circuit decreases. Two basic components
make up variable resistors. The resistive material is the first component and is called the element.
Figure: Variable Resistor
The second component, called the wiper or brush, is used to set the resistance, and is often controlled with a
knob or sliding switch. There are several different kinds of variable resistors. At Future Electronics we stock
many of the most common types categorized by Type, Number of Turns, Tolerance, Rated Power, Nominal
Resistance and Packaging Type. The parametric filters on our website can help refine your search results
depending on the required specifications. The most common sizes for Rated Power are 250 MW and 500 MW.
We also carry variable resistors with Rated Power up to 37 W. Variable Resistors can be Potentiometer,
Trimmer or Turns Counting Dial type. Variable Resistors can be found in:

Capacitor
The capacitor is a component which has the ability or “capacity” to store energy in the form of an electrical
charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable
battery.
Figure: Capacitor
Diode
A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most
diodes are made with semiconductor materials such as silicon, germanium, or selenium.
Figure: Diode
Voltage Regulator
Usually, we start with an unregulated power supply ranging from 9volt to 12volt DC. To make a 5volt power
supply, IC 7805 voltage regulator as shown in figure has been used Voltage sources in a circuit may have
fluctuations resulting in not providing fixed voltage outputs. A voltage regulator IC maintains the output voltage
at a constant value. 7805 IC, a member of the 78xx series of fixed linear voltage regulators used to maintain
such fluctuations, is a popular voltage regulator integrated circuit (IC). The xx in 7805 indicates the output
voltage it provides. 7805 IC provides +5 volts regulated power supply with provisions to add a heat sink.

LCD Display
LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications.
A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. A 16x2
LCD means it can display 16 characters per line and there are 2 such lines.

Transistor
A bipolar transistor is a semiconductor device commonly used for amplification. The device can amplify
analog or digital signals. It can also switch DC or function as an oscillator. Physically, a bipolar transistor
amplifies current, but it can be connected in circuits designed to amplify voltage or power.
There are two major types of bipolar transistor, called PNP and NPN. A PNP transistor has a layer of N-type
semiconductor between two layers of P-type material. An NPN transistor has a layer of P-type material between
two layers of N-type material. In P-type material, electric charges are carried mainly in the form
of electron deficiencies called holes. In N-type material, the charge carriers are primarily electrons.

OP-Amp
A voltage comparator is an electronic circuit that compares two input voltages and lets you know which of the
two is greater. It's easy to create a voltage comparator from an op amp, because the polarity of the op-
amp's output circuit depends on the polarity of the difference between the two input voltages.
Figure: OP –Amplifier Comparator Mode Working
Application
Comparator Circuit Working and Applications. Generally, in electronics, the comparator is used to compare two
voltages or currents which are given at the two inputs of the comparator. That means it takes two input
voltages, then compares them and gives a differential output voltage either high or low-level signal.

Working Procedure
For working with this project we have made two prototypes, our first one failed due to less accuracy. Finally we
designed a highly accurate system, in this system we use two sections, one for detecting wind speed and
humidity with temperature, another for detecting wind angle.
First section we used one IR transmitter and receiver for detecting wind speed. The 4 wind plate gives us
rotation with respect to the wind and it detects every rotation of the pole. dht 11 &22 is a multiple humidity
and temperature sensor that gives us weather information. We print all of those into a LCD display.
Second section is for detecting wind angle A GY271 compass will detect wind angle and it send to
microcontroller, micro controller process information and send to another microcontroller using rf
transmitters, in receiver section rf receiver receive data from rf transmitters and it send data to another
microcontroller, microcontroller process data and a lcd display wind angle.
V. SUMMARY OF THE CHAPTER
We use some electrical devices such as resistor, capacitor, diode, variable resistor, voltage regulator, dc battery,
moisture sensor, and some LED with all output shown in the LCD Display.

VI. RESULT AND DISCUSSIONS
Any project's output is its result. A project's success is shown in the result. By doing several experiments, we
determine whether this initiative was successful. The project's autonomous irrigation and moisture sensor
water level measurement are its results. The automatic supply of sufficient water from a reservoir to fields or
residential crops during agricultural seasons has been made possible by the construction of automatic
irrigation control systems. When the pump is turned on and off, the LCD display output is displayed using a
moisture sensor pump.
When Starting the system…
When the pump is on…..
When Pump is off
Advantage
● Main advantage of this project is to help farmers water the fields in time.
● Farmer can check water status
● Farmer can control multiple pump
● Low cost
● Real-time plant monitoring
