Automatic Irrigation System

Description

Automatic Irrigation System is playing a wideband role in today’s technology. This can be an automatic detection system, control unit, and many others. The kit presented here waters your plants regularly when you are out for vacation. The circuit comprises sensor parts built using op-amp IC LM324. Op-amps are configured here as a comparator. Two stiff copper wires are inserted into the soil to sense whether the Soil is wet or dry.

The Microcontroller was used to control the whole system it monitors the sensors and when more than two sensors sense the dry condition then the microcontroller will switch on the motor and it will switch off the motor when all the sensors are wet. The microcontroller does the above job it receives the signals from the sensors, and these signals are operated under the control of software that is stored in ROM.

Automatic Irrigation systems are sensing probes installed into the soil. These probes will sense the content of water in the soil. The data sensed is converted into a digital format using OPAMP as a comparator. This data is sensed by the controller to check the soil condition and display it on the LCD and also control the pump motor via relay and relay driver.
