    I posted this on the PICAXE forum and didn't get an answer from anyone who had tried it, but maybe there is someone here who has.

    I have built and experimented with the 555 method of using an HS1101 humidity sensor with a PICAXE as described by P. H. Anderson. (http://www.phanderson.com/picaxe/rh_count.html) That method was originally recommended by Humirel and works, but seems somewhat complex. Now Parallax (who apparently owns the HS1101) has published a much simpler method of interfacing this device with a microcontroller. It is described in this publication: http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/27920-HS1101-v1.0.pdf

    Has anyone tried this with a PICAXE and what were the results?

    Thanks.
