I have a PR52-33M that reports temperature, humidity, and typical particle size but all the particle number and mass concentrations are 0. I’ve had it running for about 24 hours. Is there some warm up period before it begins outputting these values or additional configuration that needs to be done?
Using Alpha Station, here is sensor payload after resetting the sensor.
