When I took the TMP36 from the circuit and made a 3V battery pack (2x AA batteires) I got a reading of 0.665V which I get to around 21 degrees which is fine.
When I put it back in circuit, at around 4V I get much lower readings and at 3.3V I get lower still.
This really confuses me now.
I have ordered some more, but a little upset that I seem to have killed this one.
Tonight, I will try taking out the Microprocessor and all the other bits and try just on its own incase it is just very sensative, but I have not come accross this in the year or so I have been playing.
Cheers anyway...
Jimmy
