sdsi

I've just made the mod with the antena. Now I'm testing...

sdsi

thanks. good idea.

sombedy who has got WH1081 (model without ferrite rod aerial) can write about values from humdity sensor...?

sdsi

like you - I'd like to see the correct value on the display. all photos (and nothing more) are on this page http://www.flickr.com/photos/bn37ej/sets/72157605701058879/ I wrote an message to their authors - I'm still waiting for reply. beteljuice - can you write exactly what we can do with this fix? ...

from author's site: "The W8681 uses a humidity to frequency circuit based on the sample application given on page 3 of the" scheme http://www.meas-spec.com/downloads/HS1101LF.pdf and "The calibration potentometer RV1 has been omitted" so - we ought to add the calibration potentom...

sdsi

this is the scheme - try it:
