Air-Monitoring-HAT

Air Monitoring HAT

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.

Installation

Python

• Open a terminal and run the following commands to enable I2C and Serial：

sudo raspi-config

• Choose Interfacing Options -> SPI -> Yes

• You can also use GUI method to enable SPI Go to Menu > Preferences > Raspberry Pi Configuration > Interfaces, and enable SPI

• Stack Round LCD HAT on top of Raspberry Pi GPIO Header pins.
• Make Sure SPI is Enabled (As mentioned above)
• Now clone Round LCD HAT Github repository by running below command in terminal

git clone https://github.com/sbcshop/Round-LCD-HAT.git

• Enter dowloaded directory

cd Round-LCD-HAT

• Now run demo.py by running below command.

python3 demo.py

• You can also run "LcdDemo_Joystick.py" file to display the image and change the color of the arc using the attached 5 input joystick.

python3 LcdDemo_Joystick.py
