“HAT works perfectly, just had to do some research to work out what the sensor readings "mean" (reports are in ohms, you need to process that to get something that shows the actual air quality in an easily readable format)”
“Works well with Pimoroni libraries. A few issues that I found so far: discrepancy in BME280 readings caused by heat from RPi when mounted directly above. It would be good for Pimoroni to bundle Enviro+ with GPIO extension ribbon cable. In my experience it significantly improved the accuracy of temperature and humidity readings however hasn't completely resolved it. Noise sensor library examples don't produce any meaningful output and will need digging into it.”
