Using this system, you can remotely monitor the battery level, mains voltage, battery run time, temperature. It designed using PIC16F877A microcontroller for reducing the external components, such as external ADC, OP-AMP, large number of resistors and capacitors. Lesser external components increase the circuit response and stability. And also decrease the power consumption, noise. The protection can be done by an easy manner. Temperature and battery dry run protection circuits are inbuilt. So there are no external circuits needed. It is very useful for IT industries, computer laboratories, colleges and schools.

BACKGROUND One day at the evening time I was talking with my uncle on telephone. He asked me some question base on my learning means what are you learning? which type of engineering are you doing? He ask me that have you made something new during your engineering? That time I don’t have any answer. But…
