This document describes a project to monitor and control azolla crop growth through an Internet of Things system using an ARM Cortex-M0 microcontroller. It involves collecting temperature and pH sensor readings from an azolla pond and sending the data to a website via WiFi. If the pH is too high or low, motors will pump acidic or basic water into the pond to regulate it. The system aims to optimize azolla growth conditions for use as livestock feed or fertilizer. Implementation involves interfacing sensors to an ARM processor and ESP-01 WiFi module to upload data to a cloud platform for remote monitoring of pond conditions. Results show successful data collection and control of water pumps based on pH thresholds. The system provides an automated solution

3. Abstract
 Now-a-days agriculture plays a major role in Indian economy. Farmers are the
backbone of agriculture field.As of you know there azolla plants are grown up
along with the crops. By the way it takes nitrogen and some other nutrients from
the crop and these reasons the yield will decreases. All of those reasons we
should decide to cultivate the “Azolla” plant.
 By cultivating the azolla plants we have to maintain the temperature and pH level
of water.
 Basically azolla gives 30% nitrogen to the crop and it will kills the azolla plants.
 Feeding this azolla to the buffaloes it increases the quality of the milk and
increases the production of the milk.
 By collecting the readings we can use the microcontroller, pH sensor and Wi-Fi
mojdule and then we can send the data through the website by using the Wi-Fi
module

4. Introduction
 In agriculture areas farmers are used pesticides and different types of chemicals
to increase the production and quality of the rice, by use of these chemicals and
pesticides farmers have more investment in that particular chemicals, by end of
this we have to implimente the cultivatation of azolla plants, it will grow within two
days under certain temperature condition.
 Increase the quality of rice because it produces 30% of nitrogen.
 When we feed this to buffaloes the quality of milk increases.
 Using in aqua culture it will gives more proteins to the fishes. Then we calculate
the pH and temperature readings and the it sends to the IOT platform by using
ESP-01 and then it will have cloud storage also. By thus cloud storage we have
to know what is the temperature and pH value at that particular time.

5. Literature survey
 Kasim M.Al-Aubidy et al. [3] demonstrated the construction of a rule-based fuzzy
controller for managing each greenhouse's microclimate. The projected system enable
the farmer to monitor both the inside and external surroundings of the greenhouse.
 Yunseop (James) Kim et al. [4] suggested using a wireless connection to a base
station computer to electronically manage an irrigation machine equipped with a
programmable logic controller that receives geo-referenced position updates from a
precision GPS.
 Jzau-Sheng Lin et al. [5] proposed a field signal monitoring system in precision
agriculture that uses a WSN network that combines a SOC platform with Zigbee
wireless network technology.
 Adnan Shaout et al. [6] proposed a low-power consumption and cost, robust data
gathering system capable of creating and collecting data autonomously in remote or
isolated locations. The soil moisture , temperature, air temperature and humidity, are
measured by the sensor module.

6. Methodology
 step 1: arrange the set up in poly-house for
monitoring the parameters as a input.
 step 2: the data is collected and uploaded to
the website.
 step 3: using an division/condition. if
condition is false then check the results.
 step 4: if the condition is true predict the
results and feedback to step 2.

7. Implementation
 The design and implementation of this project is done
through pH.
 pH sensor [10] is placed in water pond.By calculate the
pH we need a driver to detect the voltage[11], pH e.t.c.,
 Whenever any emergency is detected. it is displayed
on the OLED display and sms is sent to authorities
using IOT platform[12].
 The irrigation system communicates with each other
via short messages by events present in the IOT
platform.
 ESP-01[13] is interfaced with ARM Processor with the
help of USART[14] . The ESP-01 RX is directly
connected to TX of ARM Processor with controller port
pin.
 The ESP-01 has a micro chip antenna that emits
signals; the antenna responds by sending back its
data. ESP-01 communicates with TX and Rx[15]

8. Results & Discussion
 The ideal state at switched OFF and ON are
shown in Figure 3.
 pH sensor and temperature sensor plays
major role in this project . By maintaining pH
value in the range of 4.5- 10 the plant is in
living condition and in the range of 4.5-7 the
plant growth increases.
 Two sensors and ARM processors from each
node have interfaced with other nodes.
 Figure 4 is shows no suspecting condition
detected in monitor
Figure3. Idle state of the system when about to
be switched on
Figure.4. no suspicion is detected

9. Results & Discussion
 Data is uploaded in to ubi dot website through
interfacing device is shown in Figure 5.
 PH Readings gathering from serial monitor is
shown in Figure 6.
 Sending SMS through ubidot website is
shown in Figure 7.
 Whenever pH value above 10 the water motor
in the basic solution tank it will pumps water to
the plant. That the same thing happens below
4.5 water motor in the acidic solution will
turned on and pumps the water to the plants
at that time we turned on the stirrer then
mixed the water coming from motor and water
contained in the tank.

10. Conclusion
 The Aazolla cultivation system is designed with simple electronics. Two sensors, the
temperature and pH of the water in the circuit, are effectively employed to provide
calibrated data to the system.
 Two sensors and ARM processors from each node have successfully interfaced with
other nodes. All analyses and actual assessments demonstrate that the
recommended system is a comprehensive solution to growing activities and water
generation issues.
 Using such a technology in automated farming could significantly reduce molka plants
and increase milk production
