Automatic Irrigation System Using Soil Moisture Sensor Abstract

The aim of the project is to develop an auto irrigation system which measures the moisture of the soil and automatically turns on or off the water supply system.

Automatic irrigation system using soil moisture sensor abstract.

A properly configured soil moisture sensor can save up to 60 percent of water used in irrigation. Hence the system reduces human intervention and provides required irrigation to field. 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 soil moisture sensor is inserted in the soil.

The author s prototype is shown in fig. Explained in this section is a simple and exciting automatic plant watering system that you can build yourself in just a few hours. The soil moisture sensor measures the conductivity of the. It is an arduino based automatic plant watering system that uses a soil moisture sensor.

On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. 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 working of the circuit is as follows. Depending on the quality of the sensor it must be inserted near the roots of the plant.

Soil moisture and irrigation most soil moisture sensors provide measurements in the unit water fraction by volume wfv or m3m 3 and is symbolized with the greek letter theta θ. For example a water content of 0 20 wfv soil moisture and irrigation read more. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status.
