Multi-Sensor IOT-Based Smart Water Monitoring System with Real-Time Leakage and Hazard Detection

Abstract

Water management should be efficient since it assists in reducing water wastage while at the same time ensuring sustainable water consumption in the household and industries. The project works out the system of the Internet of Things that monitors and regulates water resources by means of its smart water monitoring system that runs on the ESP32 microcontroller and provides real-time data about water level, consumption, water quality, and safety. The system works on the principle of an ultrasonic sensor that identifies the level of water in the tank that triggers the pump motor by a relay module to prevent overflow and dry running conditions of the tank. The YF-S201 flow sensor is used to monitor the use of water and identify its leaks by using its capability to detect the abnormal pattern of water flow, which is never supposed to be happening in a system when it is not in use. The system employs a TDS sensor to check the quality of water by determining the level of impurities in water. The system has MQ2 and MQ4 sensors that detect gas and methane leakages to improve safety during operations near the water storage tank. The ESP32 board collects sensor information that it transmits via Wi-Fi to a cloud dashboard that can be used to monitor the device remotely and create alarm systems. The system automates the functioning of the motors by utilizing its decision logic that makes use of preset thresholds in detecting water leaks. The system integrates three technologies in its sensing and automation system and cloud connection feature that form a cost-effective system of managing water resources in intelligent systems. As demonstrated in the system implementation, various sensor Internet of Things systems are capable of enhancing efficiency and reducing water losses by ensuring the water storage and distribution systems are safer.
