Water contamination is one biggest factor for no green globalization. To prevent that and make the green globalization we need to monitor the water quality. We implement a system IoT based Public Watering System with Quality Measurement for continuous water quality measuring and alerting. In this proposed paper we implemented Internet of thins based system with pH sensor, Water quality sensor, Conductivity sensor, Flow sensor, all are integrated to the novel micro controller NodeMCU model and for IoT we used ESP8266 module for server creation and alerting to the public government dashboard.
