I want to measure small temperature differences between the temperature of the ventilation air (cooled) and the room temperature. The difference will be someting like 2 degrees C. The offset of 0,6 degrees C is a problem.
I’ve tried the DHT22 sensor in other raspberry pi projects. They need also adjusments. But thats easy in a python script or shell file.
Therefor i like to adjust te value + or - of x or /. It would be even better if I can use other measured values to calaculate a new value.
