The
main aim of this project is to operate the different loads in the
industry at different timings so that the power can be saved at a
maximum extent. The system uses the microcontroller as the most crucial
device that manages the time schedule and runs the application at
regular programmed timings without the human involvement.
This
project provides different on and off timings to switch on/off
different loads. The system operates the particular load only at
preprogrammed timings. As the DS1307 Real Time Clock chip with battery
back-up is used, there will be no disturbances for the programmed on/off
timings even in power failures.
DS1307
is interfaced to the microcontroller for real timing performance. A 3V
battery can be connected to DS1307 to avoid time disturbances caused by
power failures. The user may even change the preprogrammed timings and
set his timings according to his requirements. LCD is used to display
the status of the loads. The system stores the preprogrammed timings in
its memory.
