This project allows you to construct a Particulate Matter Sensor (PM2.5 & PM10) for outside (or inside) your home and import the data directly into HomeSeer. It uses the design from Luftdaten.info (German) using a NodeMCU v3, SDS011 Fine Dust Sensor and optional Temp/Humidity/Pressure sensors which are all available from Amazon, Ebay or AliExpress (cheaper).
Because construction is designed for non-programmers, software for the NodeMCU is provided and just needs to be loaded on the board. Your data is uploaded to Luftdaten.info where it is stored and can be used to display graphs of pollution over time. The data is not identifiable unless you opt-in and allow it to be plotted on a world-wide map to show pollution levels and assist with sensor deployments across the world.
Local data from the sensor can also be imported to HomeSeer devices (as seen below) using the script on my site.
English Home Page for Luftdaten.info can be found here.
Construction manual for the Particulate Manual Sensor can be found here.
Additional details can be found in this document.
Active Sensor Map can be found here.
For ease of construction, their design uses PVC pipe to house the components. If you have/access to a 3D printer and want a more professional housing, I used this design from Thingiverse which uses an off-the shelf electrical junction box. This design includes a DHT22 Temperature/Humidity Sensor and a BMP180 Pressure/Temperature Sensor. There are also other case designs on Thingiverse which may be suitable.
The script is available from my site (click on my banner below). Any problems, please let me know.
