Automatic Water Controller Switch and pH Determination for Water in Overhead Tank Using IoT

Abstract

Water is a valuable natural resource which is used very thoughtlessly. Ground water is pumped up to overhead tanks through electric motors for daily usage. To overcome the alarming water crisis, the unnecessary wastage of water due to overflow in overhead tanks needs to be controlled. Automatic water level controller switch is designed to overcome this concern by automating the manual switch used to control water fill-up in the overhead tank. It is implemented using water level detector and Raspberry Pi module. The water level detector made using probes detects “empty-tank” condition in overhead tank and triggers fill-up process. The switch can be controlled through mobile phone app facilitating the user to regulate the overflow anywhere outside the home also. We also propose to determine the pH of the water stored in the overhead tank enabling us to identify acidic content of the water supplied for daily use and suitably initiate necessary cleaning action.
