AN IOT BASED AIR POLLUTION MONITORING SYSTEM FOR SMART CITIES
As the world’s population is becoming increasingly urban, the cities are under pressure to remain livable. In recent years, the air quality of the cities has become one of the major causes of concern around the world. Thus, it is necessary to constantly monitor the air quality index of a city to make it smart and livable. According to the world health organization nearly eighty percent of the people living in urban areas breathe air worse than WHO standards leading to global environmental threat. Air pollution is ranked number 4 in the list of leading risk factors for death contributing to 9% of deaths annually accounting to nearly 1 in 10 deaths. With the advancement in sensing and embedded technology, Internet of Things(IoT) has become one of the economic alternatives to implement air quality monitoring systems(AQMS)compared to costly and fixed air quality monitoring stations. In this project, we propose and develop an IoT based Air Quality Monitoring System for Smart Cities. The real-time data of the air quality is accessed through the smart devices and analyzed to measure the impact on city dwellers. It will transfer the data through MQTT protocol. So that we can see the real time air quality in our mobile. The smart devices are capable of measuring the Smoke and other hazardous particulate matters in the atmosphere. This Air Pollution Monitoring System will monitor the Air Quality using a gas sensor, large amounts of harmful gasses are present in the air like co2, smoke , benzene , NH3 and No. it will trigger an alarm and we can monitor in mobile networks when the air quality goes down a certain level. It will show the air quality in PPM (Parts per Million) and like “Fresh Air”, “Poor Air”.
