Automatic Irrigation System Using Soil Moisture Sensor Abstract

Depending on the quality of the sensor it must be inserted near the roots of the plant.

Automatic irrigation system using soil moisture sensor abstract.

Automatic plant watering system circuit and working. On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. 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.

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. 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. It is an arduino based automatic plant watering system that uses a soil moisture sensor.

Hence the system reduces human intervention and provides required irrigation to field. Explained in this section is a simple and exciting automatic plant watering system that you can build yourself in just a few hours. 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. For example a water content of 0 20 wfv soil moisture and irrigation read more.

The working of the circuit is as follows. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. The soil moisture sensor is inserted in the soil.
