Abstract: The biggest issue facing the planet now is air pollution. Because harmful chemicals like CO2, SO2, NO2, and CO are released into the atmosphere, the globe is becoming more polluted. These dangerous gases are dissolved in the air and are unpredictable. Consequently, a device is needed to measure the air quality. IoT devices that operate over the internet can be used to monitor air pollution. Devices connected to the Internet of Things (IoT) can gather data and analyze it to make predictions, such as whether the air is of acceptable quality or not. As a result, sensors and IOT-based devices like Arduino and Raspberry Pi can be used to monitor the air quality in a specific area. The goal of this research study is to comprehend information on environmental variables and also to enable simple integration into any other type of internet-based architecture (IoT) that permits the use of sensors capable of gathering information on sensors related to smart city environment measurements, with the goal of providing data on information relating to environmental pollution.
