Abstract: The developed system is a device that measures and displays air and water pollution. Nowadays, water and air pollution is increasing day by day. The factors responsible for this pollution are industrialization, growing population, urbanization and so on. This has become a big problem that needs to be worked on. The air quality sensor is used to detect the pollution level in ppm with the help of Arduino. The water sensors are used to detect the water quality and indicate whether the water is harmful due to physical and chemical factors. This will help people to monitor the level of pollution anywhere and anytime.

Keywords: Arduino UNO, LCD, Industrialization, Turbidity, TDS sensor.
