A Telemetry System for Real-Time Air Quality and Noise Monitoring in Urban Areas Based on IoT Technology

Large urban agglomerations inevitably lead to air pollution. The sustainable control and monitoring of air pollution have been lacking in many cities including air quality and noise information was difficult to be accessed by the citizens periodically. This paper aims to design an air quality and noise telemetry systembased on internet communicationwhich can record the measurement data into MySQL database and showing the data through a GUI in real time. The system was developed by using solar panel as a main power supply with Arduino Uno R3 as a microcontroller board, ENC28J60 as an ethernet module and various environmental sensors like MQ7 (CO gas), MQ131 (Ozone gas), KY-038 (Noise), Dust Sensor GP2Y1010AU0F (PM10) and DHT11 (Temperature and Humidity). The system has been tested through an in-field experimentation performed in different areas of Pontianak City. Electrical energy consumption was 78,49Wh in a day. According to the test results, the system could work properly for both hardware and software.
