Hi Paul

I've used a sensor made by TDK. The device number is
CHS-GSS. It requires a 5 volt supply and produce a voltage
that ranges from 0 - 1V in 10mV steps that represents
the relative humidity between 0% - 100%.

Great little sensor!

Subject:        humidity sensor

Hi,
Awhile ago there was a thread on humidity sensors. One of the
recommended vendors was Panametrics with their RH2 sensor. This is
supposedly a low cost humidity sensor. However, their "sampling" program
is to sell me 3 for $100US. This hardly qualifies as low cost or
sampling. Does anyone have any other sources for a humidity sensor or
better yet a way to build your own?

Thanks,
Paul K.

PS I will be interfacing this to a PIC. So it is not quite OT.
