ESP32 Based Implementation of Water Quality and Quantity Regulating System

The primary purpose of this paper is to reduce the wastage of water. The former way of water testing is manual, costly, time consuming, whereas proposed work is easy to install and cost effective. The proposed work is focused on water quality and quantity measurements by using ESP32 microcontroller and Blynk for communication between hardware and phone. Water quality is monitored by the various chemical parameters of water like pH and electrical conductivity and physical parameters of water like turbidity and temperature. In addition, the quantity of water is measured by flow sensor and water level present in the tank is control by admin through the pump. Global Positioning System (GPS) is used to update the location of the water tank to save time and speedy maintenance. The result shows a good agreement with the standard values of parameters as per World Health Organization (WHO).
