problem with hs1101

Hello everyone,

I am playing with a BS2 homework board and a hs1101 sensor. I have programmed the BS2 with the example from the hs1101 datasheet and all I get at the serial terminal is:

Relative Humidity is 2223% and it never changes. the board is new and I have checked all my connections. are these sensors any good?

    So no one uses these sensors? I can see why.

    A schematic and the code you are using will help with answers. (maybe) Post your actual code using the "CODE" tags to keep the formatting.

    The HS1101 sensor is basically a capacitor which varies with relative humidity. It's a very simple device and there isn't any reason why it shouldn't work with the correct hardware and software.

    I've just ordered a couple of them to play with, from Parallax. They don't seem to be available from any of my usual UK suppliers.

    I'll probably interface one to a PIC.
