Pico Air Monitoring Expansion
The Pico Air Monitoring Expansion is a HAT for Raspberry Pi Pico that measures suspended particulate matter (PM1.0, PM2.5, and PM10) in the air. It uses a PMSA003 digital laser dust sensor and includes an onboard 0.91″ OLED display for real-time readings.
The board communicates with the Pico via UART and also breaks out additional GPIO pins for connecting external peripherals and sensors.
