Hi duino_nano!
I just run dht11 under nano (Chinese clone) and it says that humidity in my room is about 512% RH while temp. is around 537 C. )) I'm on good Earh not on Venus so far. Log is attached (knob - is my finger's applied just against the sensor)... What d'u think of it guys?
VDD 5V (const) - well I've read in dht's DS that it isn't good to supply it with DC current due to polarization of the gauge.
