AirGradient DIY Air Quality Sensor


AirGradient has created a DIY Air Quality sensor. They offer a PCB, PCB + components kit, etc. A pretty neat package. To use this you have to run their software but you can use the kit with ESPHome as well!

Here is what it can measure:

  • Temperature

  • Humidity

  • Air particles PM2.5

  • Carbon Dioxide


  • There is a display so show off your data or whatever you desire from Home Assistant
