Automatic plant irrigation using Microcontroller

SECTION 1: PROJECT TYPE

Micro controller (AT89C51) hardware design with software development (Device Driver). Atmel micro controller (AT89C51) based.

SECTION 2: PROJECT DESCRIPTION

         

The Project presented here waters your plants regularly when you are out for vocation. The circuit comprises sensor parts built using op-amp IC LM324. Op-amp’s are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense the 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 in wet. The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.
