Automatic Irrigation System Using Soil Moisture Sensor Abstract

Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status.

Automatic irrigation system using soil moisture sensor abstract.

Multiplying the water fraction by volume measurement by 100 will equal the volumetric percent of water in soil. Explained in this section is a simple and exciting automatic plant watering system that you can build yourself in just a few hours. Depending on the quality of the sensor it must be inserted near the roots of the plant. 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 working of the circuit is as follows. The author s prototype is shown in fig. Hence the system reduces human intervention and provides required irrigation to field. Automatic plant watering system circuit and working.

The soil moisture sensor measures the conductivity of the. 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. The soil moisture sensor is inserted in the soil. 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. A properly configured soil moisture sensor can save up to 60 percent of water used in irrigation. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.
