PT1000 difficulties on TinyESP wifi controler
Posted: 30 Jun 2023, 10:40
Did someone successfully connected PT1000 platinum thermometer to analog input of TinyESP device running "ESP Easy Mega: TinyESP-WiC " ?

Just connecting two sensor pins on analog input pin and gnd pinbon P1 port does not seem to work as the device configured as "analog internal" measures valies that do not correspond with resistivity change of the PT1000 sensor. The voltage neasured on sensor connected to the device gives 4.30 +/- 0.03 V on 29 degC or -15 degC and drifts randomly among 4.27 and 4.33 V.
Thanks for any response.
