Abstract :
Previously, many technologies regarding control systems included clean
water supply systems using 2 pumps, 2 water tanks, 1 as a tank as a tank under
ground tank and 1 as a tank tank. Use WLC (water level control) to control the
pump life of the pump based on the water level in the tower tank. The control
system is the control of one phase and 3 phase motors. In the control system there
are important components such as contactors, relays, Arduino, keypads and many
more. The control system can be operated manually and also automatically.
