Hey all.
I recently purchased a moisture resistive sensor over Ebay similar to this:
http://www.ebay.co.uk/itm/Soil-Mois...0-/291193484418?ssPageName=ADME:X:AAQ:GB:1123
Now it only has the three pins Vs Ground and signal which it states is an analog output. Now having received it and tryed it out on an little GSM Modem I have through the analog input all I am getting is a digital value output from my modem of -10. This does not change be it dry or wet.
So im not fully sure whats the problem as I have no datasheet so hope one of you guys have had some experience with one or know where im going wrong.
thanks.
