Today we're meeting to discuss:

The upgraded air quality display (particulate matter), now with a web interface, tracking 32 locations with 4 sensors each, and an interface to the Telraam project (traffic counts). This is InfluencAir's own development, and suggestions for adjustments and improvements are welcome, including collaboration on further development or extension of the supported languages of the display's software. The source is public domain (GNU GPL V3) and is published on GitHub (displayPM_32x4)

Stand-alone displays of 53cm long can be built during this session. Materials for this will be provided for a contribution of €40 per display.

One application of this display will be demonstrated: our Zuivere Lucht Dilbeek project, which runs through the 2025/2026 school year, has installed 17 air quality meters in schools, each equipped with a modified version of this display. The sensors in the meters include a basic SDS011 particulate matter sensor, a humidity-compensated SDS011, and a SEN55 for measuring particulate matter, VOCs, and NOx. The entire project in Dilbeek also includes 120 basic meters with only a basic SDS011 particulate matter and a BME280 temperature/humidity/air pressure sensor.

Bring your laptop.
