Today I find this text, on a webpage...
Almost everywhere, I find this misunderstood about the role of the Temp / Hum sensors on air quality measurement devices. They aren't there to provide precise readings of the outdoor temperature / humidity. They are there to provide Temp / Hum data as seen by the Dust Sensor, and to allow the software to do the required corrections, specially against the %RH. That's why the T/H sensor should be placed near to the dust sensor, ideally in the air intake path.
Quote:The design suggested by the community was not applicable for my environment by using such gray PVC elbows. Our flat has only a South – South-West view and using such housing for the sensor would lead to incorrect and elevated temperature readings because of the direct sunlight during the day.
