De-coupling.

Yes, inaccurate readings when i connect the TMP sensor.

Yes, i am feeding the sensors with the Arduino :smiley: I think i tried with external power supply in the past.
I can't remember because i tried tons of things :slight_smile: I can try again if you want after seeing the values.

Please check the results, do you think there is something wrong?

Note: I am waiting someone to ban me from the forum :smiley:
