Abstract: In recent years, because of the faster advancement in the computer technology like IOT, it's easy to prepare a smarter, reliable and cost effective model in developing countries to handle one of basic need ‘water’. The basic idea of the project is to determine the quality of water by measuring the contamination with the help of sensors, then transferring the sensed data to cloud where decision making is done and the final results will be intimated on the mobile device. IoT proves to be beneficial by providing real-time monitoring. The technology uses MQTT protocol for sending data from Arduino board to any distantly located server, broker application or cloud and receives data from same to any mobile application or web application.
