Hi all,
i have a very strange problem reading the temperature of an PT1000 temperature probe with a MAX31865 amplifier module.
I use the Adafruit library to get the temperature: GitHub - adafruit/Adafruit_MAX31865: Arduino Library for Adafruit MAX31865 RTD Sensor
When the ESP32 boots up I don't get a correct reading.
Only after disconnecting the VIN Pin and reconnecting the VIN Pin, the readings are correct.
After putting the ESP32 in deep sleep and waking it up the readings are incorrect again.
Workflow:
ESP32 boots up -> false reading -> Disconnect VIN -> Connect VIN -> correct reading
Does anyone know what the problem could be. I tried to setup the temperature sensor with a delay of a few seconds but this did not solve the problem.
Thank you very much
