Abstract

Here in this project we are going to build a RTC BASED TIMER FOR MOTOR CONTROL .This project is also used in the time management motor control system, etc...

Here we use parallel RTC DS12887 for real time management and AT89s52 for control switching the bell. This project works in 24 Hours mode with six different alarm timings for switching the MOTOR on/off.

This project can maintain the time even if the power is failure for 10 years with the accuracy of ±1 minute. Here the alarm values are keeping maintained as same on power failure. It retains the real time and alarm times on power on. So there is no need of setting for every power on.

For user interaction we use lcd and key pads. These key are used to set the actual time, setting the six different alarm times and six different alarms on times
