Janusz 20.03.2023 Confirmed purchase Translated review
The DHT sensor easily works with e.g. with Raspberry Pi PIco enabling direct reading of relative humidity and temperature. For example, in the MMBASIC (PicoMite) language, the measurement results are read with the command BITBANG HUMID pin, tVar, hVar. I use the DHT22 sensor to calibrate other relative air humidity sensors.

The sensor met the expectations and most importantly that it works perfectly (different, probably the same, but not too much cheaper).
