Pico Air Monitoring Expansion

The Air Monitoring Expansion for Raspberry Pi Pico is an open-source, portable sensor that measures suspended particulate quantity by mass. It operates at 5V and features a digital laser dust sensor (PMSA003) and a built-in 0.91" OLED display providing information on air particulate matter (PM1.0, PM2.5, PM10) via digital output. Communication is done through UART (serial), and it offers external GPIO Breakout Pins for connecting sensors.

Note: Raspberry Pi Pico is NOT included
