e-Rigation
This project called e-Rigation consist of microcontroller & PMDC motor for Efficient irrigation

Solution

This project involves microcontroller with the conventional solar panels for irrigation system. 

the solar tracker as well as mirrors on solar panel help in increase in the efficiency of solar cells thus the output of solar panel increases.

this is a youtube video showing how solar panel power can be boosted up through mirrors.

the system is microcontroller controlled, which helps in automatic irrigation and water management.
sensors interfaced with 8051 microcontroller controls the amount of water to be delivered to the field making it totally automatic and most efficient system for irrigation.

The extra energy is also stored in a Lead Acid Battery and provide electricity to the farmer's home.
