A PCB for the airrohr project located at luftdaten.info, a citizen science project to measure air particles (PM10 & PM2.5).
This is just for these PCB's and not for a complete airrohr sensor altough the only thing you need besides this list is a SDS011 particle sensor.
Solder on all the headers/sockets that you want to use for your project
Use the nylon spacers and screws/nuts to mount the board to the bottom of the SDS011 sensor and then connect the cable between the sensor and the board:
The complete package is designed to fit into the 75mm sewer pipe system that the airrohr project uses for mounting and securing the sensor:
