Air Monitoring Expansion for Raspberry Pi Pico is an open-source portable sensor that has the ability to provide the level of quantity of the suspended particulates with their mass. Pico Air Monitoring Expansion works on operating voltage of 5V with a hi-tech Digital Laser Dust Sensor, PMSA003, sensor with on-board 0.91" OLED Display, that provides the information of suspended particulate matter(PM1.0, PM2.5, PM10) in the air per unit volume via digital output . It communicates via UART(serial). External GPIO Breakout Pins are also available to connect the external peripherals and sensors with it.
Note: No Pico board Included
