May 06, 2021· The heater should warm the sensor, after 5 or 10 minutes the metal of the sensor should get warm. The ''signal path'' is like this: 5V to both ''A'' pins > ''A'' to ''B'' is the sensor > both ''B'' pins to resistor and to analog input > resistor to ground. Also, 22k is very high. The output could be at the maximum. I would suggest to use 2k2 to start ...
