The AirGradient DIY Air Quality Sensor (Basic Version PCB Version < 3.0)
Please note that this is a legacy instruction for people having the DIY BASIC PCB labelled with “PCB v2”. The version number is written on your PCB. If you have a different version please find your correct build instructions in this overview.
As part of the Open AirGradient movement, this instruction teaches you how to build a compact and powerful air quality monitor with AirGradient.
The monitor displays PM2.5, CO2, temperature and humidity and can optionally send the data to the AirGradient platform or any other cloud backend for data logging.
You will need some basic soldering skills, and experience with microcontrollers is a plus. However, even if you are a beginner, you won’t need to worry because we made the instructions really easy!
If you want to build a monitor with a larger display, a better enclosure and more extensibility, check out the DIY Pro instructions.
