Automatic Irrigation System Using Soil Moisture Sensor

An lcd display to show the moisture percentage and pump status.

Automatic irrigation system using soil moisture sensor.

The soil moisture sensor measures the conductivity of the. Here we are building a iot based irrigation system using esp8266 nodemcu module and dht11 sensor. The automatic irrigation system on sensing soil moisture project is intended for the development of an irrigation system that switches submersible pumps on or off by using relays to perform this action on sensing the moisture content of the soil. Automatic watering system using fc 28 moisture sensor with arduino by admin published november 20 2017 updated april 17 2020 automatic irrigation is a concept of controlled watering of plants without any manual operations so as to maintain a water level ideal for its cultivation.

The working of the circuit is as follows. I have used a self made water pump in this system using 5 volt dc motor. On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.

A relay module which used. The main advantage of using this irrigation system is to reduce human interference and ensure. Depending on the quality of the sensor it must be inserted near the roots of the plant. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status.

The smart irrigation system has wide scope to automate the complete irrigation system. After which the water pump will automatically get stopped. As plant get sufficient water and soil get wet then sensor senses enough moisture in soil. The ideal setting for using soil moisture sensors to manage the irrigation in this challenging environment.

The soil moisture sensor is inserted in the soil. The automated irrigation system is a fully functional prototype which consists of a soil moisture sensor. Simply install a sensor in each of the zones and then set up a watering strategy for each location. It will not only automatically irrigate the water based on the moisture level in the soil but also send the data to thingspeak server to keep track of the land condition.

The system reads the moisture content of the soil using soil moisture sensor and switches on the motor when the moisture is below the set limit.
