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.

Features

Digital sensor
Operating Voltage 5V DC
PMSA003 Sensor
Standard 40 Pin GPIO
OLED Display 0.91”
Measuring range 0.3 to 10 Micron

Installation

Python

Required Hardware

Raspberry Pi x 1
RFID HAT x 1

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
