Arduino Air Quality Monitor - Arduino Project Hub

The open, local, real-time air quality data from PurpleAir has been super valuable during the pollution we've experienced over the past few months. I was also happy to see they even used the Arduino IDE to create this product!. I've found myself checking PurpleAir's map multiple times a day - then realized the Arduino could just read the value itself and display the color on an LED display - so you would always …

Arduino Based Air Pollution Control - EngineersGarage

The Arduino keeps reading the CO2 level from the gas sensor and if the current CO2 level increases beyond the threshold level, it activates the buzzer and sends a HIGH logic to relay connecting pin switching the air purifier ON. When the CO2 level is again reduced to a permissible level, the Arduino switches OFF the air purifier by sending a LOW logic at the relay connecting pin.
