Outdoor Automatic Air Purification Redefined with Air Quality Monitor

This research study aims to design and build a solar-powered air quality monitoring and filtering system to reduce air pollution by removing harmful particulate matter from the air using eco-friendly methods. The system utilizes sensors such as MQ135 for air quality and MQ6 for gas contamination and converts their output to digital data using an ADC. The Arduino Uno board with 6 ADC channels is used to display the calibrated sensor data on an LCD. The controlling fan of the filter regulates the filter fan to filter out air by setting threshold values, with the help of a relay.
