Automatic Water Supply and Monitoring Using IoT

Abstract

The use of IoT technology in the water supply and monitoring system aims to tackle the issues of insufficient and unreliable water supply, as well as water wastage, prevalent in developing nations. The system comprises four sub-tanks, one overhead tank, an Arduino Uno board equipped with ultrasonic sensors to detect water level, an L298N motor driver module for regulating the submersible motor pump, and an ESP8266 Wi-Fi module for internet connectivity. The Firebase platform-based mobile app enables users to view the water levels in each tank and operate the motor. The water supply system is designed to manage the water supply efficiently, prevent water wastage, and ensure the water levels in all tanks are continuously monitored in real time. The four ultrasonic sensors measure the water levels, and the L298N motor driver module operates the submersible motor pump. The system regularly checks the water levels and activates the motor pump when the water level in any of the sub-tanks falls below a certain threshold level. Once the water level reaches the upper threshold level, the motor pump is deactivated. Users can view the water levels in all tanks on the mobile app and operate the submersible motor pump manually. This system provides a dependable and efficient approach to managing water supply, ensuring the water levels in each tank are continuously monitored and maintained in real time. The low-cost design makes this an affordable solution for water supply and monitoring in developing nations, promoting effective management of water resources.
