Return of the Air Quality Sensor

This week I got a call from John who has been building some more air quality sensors for deployment around Cottingham. These connect via WiFi and are designed to wake up, sample the data, and then go back to sleep for a while. Such are my data management skills that it took me a few minutes to find the original files and build the firmware. My software worked fine, but it looks like the BME280 sensors that we are trying to use are not working. I’ve seen this problem with these before. People are quite happy to label all kinds of other devices as BME280 compatible, or change the I2C addresses of them. Anyway, hopefully we’ll get some working ones soon and do a bit more air quality monitoring.
