Abstract— Water, the foremost crucial contingents of life forms. Pollution is the most important fears for the green globalization. Therefore, the safe supply of beverage and use water for various purposes like agriculture, the water should be monitored. The system is meant so as to watch the standard of water using internet of things (IoT) to see its containment and confirm to eradicate its impurities. This article presents low costs system for time monitoring of water quality system. We’ve used Temperature, pH, Turbidity, etc sensors. The temperature sensor detects the degree of hotness and coldness of the water. The ESP-32 model is often used as a controller. The measured value of the sensor is processed by the controller. Finally, the sensor data are often shown on IoT based system. The information then received is employed within the purification of impure water through IoT functioning.KEYWORDS: Internet of Things, Temperature Sensor, Turbidity Sensor, Flow Sensor, pH Sensor ESP-32 Model.
