An automatic water level switch.

Abstract

The main objective of this research to design and develop an automatic water level switch and preventing the wastage of water due to over pumping. This report describes the design, development, implementation, and testing of an automatic water level switch and reduce on the wastage of water. The device controls the pump depending on the water level. Two float level sensors are used to detect upper and lower water level points. When the water falls below the lower point, the pump is switched on through the relay. When the water level reaches the maximum, the pump is switched off.
