Open Source Air Quality Monitoring Kit

General

Hello

I have developed an Air Quality Monitoring Kit around a Raspberry Pi5. It has support for 7 air pollutants (NO2, O3, CO, TVOC, NOx, CO2, Radon), 2 dust sensors (PMSA003) and 6 environment parameters (temperature, relative humidity, pressure, noise level, visible light, UV).
The open-source software is written in Python and available here: GitHub - cristeab/aq_dashboard: Air Quality Dashboard.

Hi Bogdan,

This is very cool - thank you for sharing!

One question - could an older Raspberry Pi be used? I have my 5 currently running Home Assistant, but I have some older ones that are currently just collecting dust.

Hi Ethan
Any Raspberry Pi is fine. The available I/O interfaces are important:

  • I2C: for most air pollutants sensors
  • USB: for dust sensors, the microphone and CO2 sensor
  • BLE: for Radon sensor from Airthings
  • WiFi or Ethernet to access the web interface
    regards

Awesome! I will see if I can source the components (I already have most of them) as I would love to give this a shot.
