I have only been half following this thread so my apologies if this information has already appeared but what is the manufacturer and part number of the thermistor or what does it look like, size, packaging etc. Regards Chris Hello, sir Peres! =) The current is 200uA. I try to display the temperature data on an LCD, but the reading takes more than 10 minutes to be stable, meaning the change is very little. Why is this so? "Peter L.
