Automatic Irrigation System Using Soil Moisture Sensor

As plant get sufficient water and soil get wet then sensor senses enough moisture in soil.

Automatic irrigation system using soil moisture sensor.

A relay module which used. Here we are building a iot based irrigation system using esp8266 nodemcu module and dht11 sensor. Hence the system reduces human intervention and provides required irrigation to field. On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump.

The soil moisture sensor is inserted in the soil. An lcd display to show the moisture percentage and pump status. The ideal setting for using soil moisture sensors to manage the irrigation in this challenging environment. 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.

Depending on the quality of the sensor it must be inserted near the roots of the plant. I have used a self made water pump in this system using 5 volt dc motor. I could use 12 volt water pump in the system but to operate this it will require a relay module. The soil moisture sensor measures the conductivity of the.

Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. 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. The automated irrigation system is a fully functional prototype which consists of a soil moisture sensor. Automattic irrigation and plant watering system using arduino and soil moisture sensor this project is about a moisture sensing automatic plant watering system using arduino uno.

The main advantage of using this irrigation system is to reduce human interference and ensure. The smart irrigation system has wide scope to automate the complete irrigation system. 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. Simply install a sensor in each of the zones and then set up a watering strategy for each location.

The working of the circuit is as follows.
