Hello everyone...It has been a long time since someone wrote something on this thread. Anyway, I have a Sensirion SHT-1x from Parallax (the one with the compatible carrier for breadboards etc) and an Arduino Duemilanove. I tried out these two:
and some more. I think that both of these should be working but they don't. In the first one I get an ack error 0, that means the sensor doesn't even get a command. Afterwards, I get a ack error 2 and some wrong measurements. I checked the datasheet and everything looks fine to me, it should work.
In the second link, since it doesn't do any error handling, I just get 615 degrees Celsius. Of course any measurement in both the examples doesn't change if I put my finger on the sensor.
I'm having exactly the same results as described by constanton above.
Would greatly appreciate any assistance as this is really holding me up and I've been bashing my head against the datasheet with no luck for a while now.
hey constanton, be sure to use the datasheet from parallax and not the sensirion one. the parallax board swaps pins a bit and you need to connect data,clk,gnd on one side and V on the other. good luck.
