Abstract

An automatic water level controller is developed with pump switching system for both overhead and underground tanks to save electrical and water resources. The system monitors and displays level of water in the tank. The design consists of power supply, microcontroller, sensor, display and pump units. Arduino UNO, a microcontroller, is replaced with a cost effective, electronically and environmentally rugged assemblage from available cheap components. The 20kHz ultrasonic distance sensor, remotely senses level of water by measuring length of emptiness or fullness of the tank from recorded time of arrival of echo from water surface. This length is interpreted and displayed on Liquid Crystal Display (LCD) unit.
