3. Introduction
Agriculture is the backbone of all developed countries .
Monsoon dependent Bangladesh Agriculture.
Nowadays, for irrigation, different techniques are available
which are used to reduce the dependency of rain
 With the help of smart irrigation system we can solve these
in an efficient way.
With the help of sensors value we can know the weather
report, soil condition and make step for improvement

4. Objectives
 To save water and reduce human intervention in
the agriculture field.
 Continuously monitoring the status of soil
through sensors and provide signal for taking
necessary action.
 To get the output of the sensor and provide water
to crop.
 To observe parameters for better yield.

5. Proposed System Methodology
Acquisition block: This block consists of Soil Parameters like soil
moisture, pH are measured and the temperature sensor which
measure the temperature from the soil, air and water.
Microcontroller block: In this block, NodeMCU is the
microcontroller which is the core hardware of this project. It receives
the input from the soil and processes the input based on the
requirement coded in the microcontroller.
Monitoring block: This block includes an LCD display and Blynk
apps which is used to monitor the level of soil position.

7. Requirements analysis
1. NodeMCU ESP8266
2. Sensors
3. Extension board
The system also consist of Water pump, LCD display.

8. NodeMCU ESP8266
 The NodeMCU ESP8266 is a microcontroller
board based .Tensilica 32-bit.
 Operating Voltage: 3.3V
 Input Voltage: 7-12V
 Digital I/O Pins (DIO): 16
 Analog Input Pins (ADC): 1

9. Sensors
Three sensors used in the system
which are mainly as follows:
1. Soil moisture
2. Three way soil meter
3. Temperature Sensors

10. Soil Moisture Sensor
 Operating Voltage: 3.3V to 5V DC
 Operating Current: 15mA
 Output Digital - 0V to 5V, Adjustable trigger
level from preset
 Output Analog - 0V to 5V
This sensor uses the two probes to pass current
through the soil, and then it reads that resistance to
get the moisture level.

11. Three way soil meter
 Three different soil test meters in one device;
Measures moisture, pH/Acidity, and light.
 100% Accuracy; Easy to read moisture, pH and
light levels; Perfect monitor for growing healthy
plants.
 Scientifically accurate

12. Temperature Sensor
 Usable temperature range: -55 to 125°C
.
 9 to 12 bit selectable resolution
It is water proof and is used to measure air,
water and soil temperatures precisely.

Value of Soil Moisture
temperature and Soil pH
Apps show the value
Measuring the pH value

15. APPLICATION AND FUTURE WORK
In IoT-based smart farming, a system is built for monitoring the crop field with
the help of sensors ( temperature, soil moisture, pH etc.) And automating the
irrigation system. The farmers can monitor the field conditions from anywhere.
 .In this system we can also add some sensors like NPK sensor which gives us nitrogen,
potassium and phosphorus values. These values can be used as the lacking fertilization.
It can makes the system suggesting the fertilizer for the testing soil.

16. Conclusion
We provide an approach of a specific soil to predict suitable crops to grow.
Hopefully this approach will be developed in future as part of further contributions
in agriculture sector and play an important role to increase the productivity of the
crops.
