Hi all, I have a Celsius sensor connected to an Arduino Uno via a BR logic level convertor. When running the standard example sketch I am getting air temperature readings about 1 to 1.5 deg higher than expected (checked with a K type sensor). I am careful to ensure that the sensor is away from the micro controller and any possible heat source.
Interesting when I handle the sensor there is an obvious thermal storage/release effect where the senor readings increase for few minutes after I isolate the sensor (i.e stopped holding it) and then the readings slowly fall at a rate of 0.01 deg every 20 s. The base readings always tend to be 1.5 deg above what is expected.
So has anyone had similar experiences with the Celsius sensor or do I have a dud?
I would appreciate any guidance.
