It is an arduino based automatic plant watering system that uses a soil moisture sensor.
Automatic irrigation system using soil moisture sensor abstract.
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.
Multiplying the water fraction by volume measurement by 100 will equal the volumetric percent of water in soil.
Depending on the quality of the sensor it must be inserted near the roots of the plant.
The soil moisture sensor is inserted in the soil.
The working of the circuit is as follows.
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 idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.
For example a water content of 0 20 wfv soil moisture and irrigation read more.
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.
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.
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.
