Automatic Irrigation System Using Soil Moisture Sensor Abstract

The working of the circuit is as follows.

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. The soil moisture sensor is inserted in the soil. Automatic plant watering system circuit and working. 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. For example a water content of 0 20 wfv soil moisture and irrigation read more. The soil moisture sensor measures the conductivity of the. Hence the system reduces human intervention and provides required irrigation to field.

The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. A properly configured soil moisture sensor can save up to 60 percent of water used in irrigation. Depending on the quality of the sensor it must be inserted near the roots of the plant. It is an arduino based automatic plant watering system that uses 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. 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 author s prototype is shown in fig.
