Automatic Soil Irrigation System

Abstract

This project is developed for the users to control irrigation in wireless manner. The device will automatically switch off the pump when there is enough water and also switch on the motor when the soil is dry. The heart of the circuit is the IC ULN 2003, Microcontroller PIC 16F877A. There are two probes connected with the soil. Both the probes are connected with little gap. When the water is enough to the soil, the sensor sends signal to the driver IC and it sends signal to the micro controller. The microcontroller sends corresponding signal to the driver and control the pump motor through microcontroller. The motor controller controls the driver unit and corresponding relay to switch off and on the motor. Also when the soil is dry, the motor controller switches on the motor. Since it uses microcontroller for controlling operation, the operations will be very sensitive. The microcontroller program is written in Embedded C language.
