This is a web enabled PM2.5 monitor. It was designed to be cheap and easy to build. It uses a Photon as the microcontroller and a shinyei PPD42 air sensor. The full instructions and research can be found at https://airquality406.wordpress.com/
In this step you will get the photon connected to your wifi and communicating with the cloud.
This step shows you how to put the operating code on your photon.
This shows all the steps required to build the air sensor.
If you are interested in changing the code.
