Pico Air Monitoring Expansion
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.

Installation
MicroPython
- Stack Raspberry Pi Pico on the female header of Pico Air Monitoring Expansion.
- Connect USB cable on Raspberry Pi Pico USB port.
- Choose interpreter as MicroPython (Raspberry Pi pico).
- Download Pico air monitoring expansion repository from the below link:
Source code: https://github.com/sbcshop/Pico-Air-Monitoring-Expansion
- Open Thonny IDE and create 2 new files as "ssd1306.py" and "pmsa003.py" with the same content of the file you have downloaded from the above repository or you can also save these 2 files in raspberry pi pico from the file menu -> save as and select raspberry pi pico
- now open "Board_Test.py" file in thonny IDE and click on the green play button to run the code. It will display the value of PM 1.0, PM 2.5, and PM 10 on 0.91-inch OLED display.
