Automatic liquid control system for overhead storage tank in households

Abstract

The scarcity of drinking water in near future attracts the attention of the researcher how to control the use of water as per the need. Now this is a major global problem rising in front of all to avoid the crisis of fresh water. Hence, it is not only extremely crucial to preserve and save water but also to reduce the unnecessary use of water. Especially, in many houses in India, there is unnecessary wastage of water due to unnoticed water leakage from faucets and overflow in overhead storage tanks. This is where automatic liquid control system comes into picture. The operation of liquid control system is based upon the fact that liquid primarily water acts as a hindrance for sound waves emitting from the ultrasonic sensor. Rise and fall of water level results in triggering on and off switch which further enables or disables the motor pump as per the requirement. This paper has achieved its primary objective i.e. noncontact liquid monitoring system employing Arduino Uno.
