Automatic Irrigation System Using Soil Moisture Sensor Abstract

Explained in this section is a simple and exciting automatic plant watering system that you can build yourself in just a few hours.

Automatic irrigation system using soil moisture sensor abstract. For example a water content of 0 20 wfv soil moisture and irrigation read more. The soil moisture sensor is inserted in the soil. Multiplying the water fraction by volume measurement by 100 will equal the volumetric percent of water in soil. The author s prototype is shown in fig.

Automatic plant watering system circuit and working. The soil moisture sensor measures the conductivity of the. Hence the system reduces human intervention and provides required irrigation to field. Depending on the quality of the sensor it must be inserted near the roots of the plant.

The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. 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. A properly configured soil moisture sensor can save up to 60 percent of water used in irrigation. 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 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. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump.
