The
main aim of the project is to provide the water supply to different
localities in a city at different scheduled timings. 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 provide the water
supply to different localities. The system starts the water supply to a
particular locality 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.
Thus,
at the preprogrammed timings, the person operates the valve to start
the water supply from the control room. An audio indication is provided
to alert the operator to perform accordingly. LCD is used to display the
timings and also display the name of the current locality to which the
water supply is provided.
