Despite water covering 71% of the Earth's surface, only 1% is suitable for drinking, and this limited precious resource is dwindling each year. It is a collective responsibility to conserve water and guarantee a steady supply of clean drinking water. Household overhead tanks are typically filled by centralized pump units, a situation that often leads to overflow if left unattended. This is a widespread problem encountered by numerous homeowners. When a water tank runs empty, someone needs to manually regulate the motor. In this paper, a prototype Internet of Things (IOT) & GSM-integrated automated system has been developed for monitoring and controlling water pumps. A water level sensor is employed to monitor water levels. Users can turn ON the motor pump and check the water level using an Android application via IoT whenever water surpasses or falls below a specific level. This way, users, specifically farmers from remote areas, can oversee and control all operations conveniently through their mobile devices. The system under consideration operates without requiring user intervention unless the water tank is empty. The system facilitated by an Arduino Nano enables notifications about the tank's water level and active status to be sent to a designated mobile number. This system allows users to decide whether water is required in the tank by responding accordingly. The developed system not only conserves electrical power but also prevents artificial flooding, promoting a cleaner environment. [ABSTRACT FROM AUTHOR]
