PIC Microcontroller Based Real-Time Air Quality Monitoring System

The main objective of this project is to control air pollution by designing and implementing an Air Quality Monitoring (AQM) system. To reduce air pollution, and also to reduce the health issues caused by air pollution, the air quality monitoring system plays a major role. The air quality monitoring should be capable of measuring the air quality parameters. The parameters to be considered are temperature, humidity, carbon monoxide, low concentration ozone gas, and dust particles. Finally, all the sensor data will be processed by the PIC Microcontroller and the output can be displayed with the help of LCD Display. This air quality system also alerts when the air quality level is greater than the normal value using a buzzer
