A Smarter DIY Air Filter

Per Hackaday, maker Kishan Pratap Singh designed AirSense, an ESP32-powered air filter that monitors the air it outputs. The system measures PM two point five dust concentration, air quality index, temperature, humidity, and atmospheric pressure from the exhaust stream.

The result is a practical DIY solution for anyone curious about their indoor air quality.
