This project takes PM1.0, PM2.5, and PM10.0 measurements from a PMSA003I particulate sensor and provides them to HomeKit for display on iOS and macOS devices without the need for an additional bridge.
- Adafruit PMSA003I Air Quality Breakout - STEMMA QT / Qwiic
- SparkFun Thing Plus - ESP32 WROOM (USB-C)
