Temperature: 25°C, voltage 5v.
Linear response from 0.8 to 3.9v for 0 to 100%RH
The humidity sensor is a precision instrument, if you
want to use a temperature compensation use
this formula¡: (5E-05*RH -
0.0036)*T + (-0.0013*RH + 0.0925) + Vout . The temperature compensation
at 25°C, 50%RH is zero)
So, the voltage output will be: Vout = (0.0157*Vin -
0.0475) * RH + (-0.6536*Vin + 4.068)
