Next circuit is showing how to use humidity sensor HCH-1000 for reading the relative humidity of the air and convert it to analog voltage.

More information how does this circuit works you can find in "Project Documents -> Application Notes ".

Something that is not mentioned in the AppNote.For this circuit you need reference voltage supply.

Whit the PCB that develop the sensor capacity is 360p - 420p not 330-390p.

The frequency is 52.8kHz, but overall the circuit is not so accurate as the honywell says.
