My ESP8266 + Plantower AQ sensor project

This project is an ESP8266 combined with an AQ sensor and temp / humidity sensor. I have these set up around my house so I can monitor air quality and temp. It broadcasts the sensor information over UDP, and anything listening for the UDP broadcasts can decode the information and use it.


Here is a photo of the completed project:

The sensor gets power over USB. When you power the sensor up, it will create an ad-hoc wifi network. You can connect to that network then configure the sensor with the network you want it to connect to.


The PCB is found in the pcb directory. It's just a Kicad project. The README in that folder has more information about the hardware side of this project (including parts, etc).


The firmware is found in the firmware directory. The README file in that folder has more information about the firmware side of this project.


There is a sample client in client.rb. It will listen for sensor data then print it to the terminal. You should decide what to do with that data. Personally, I am feeding it in to an InfluxDB and then using Grafana to plot the data:
