Air Monitoring HAT (Incomplete Wiki)
Air Monitoring HAT is a powerful and hi-tech PMSA003 sensor that provides the information of suspended particulate matter (PM1.0, PM2.5, and PM10) in the air per unit volume via digital output with an operating voltage of 3.3 V. It communicates via UART (serial) with the standby current ≤200 Microampere (μA) of the sensor.

Enable I2C and Serial Interface
- Open a terminal and run the following commands to enable I2C：
sudo raspi-config
Choose Interfacing Options -> I2C ->yes
- Again run below command to enable Serial
sudo raspi-config
Choose Interfacing Options -> Serial -> No -> Yes
- You can also enable Serial and I2C using Graphical method, Open Menu by clicking on Raspberry Pi icon >> Preferences >> Raspberry Pi Configurations >> Interfaces , and select below option.
- Now reboot your pi by running the below command :
sudo reboot
Board Test
- Clone Github repository of Air monitoring HAT by running below command and enter its directory.
git clone https://github.com/sbcshop/Air-Monitoring-HAT.git cd Air-Monitoring-HAT
- Now run GUI of Air monitoring HAT by running the below command on terminal.
