Read the thermocouple’s cold junction (the connection between the wire of the thermocouple and the connector or the screw terminal) temperature value. This value is used to compensate the temperature reading of the themocouple’s hot junction.
THERM.readReferenceTemperature()
None.
The thermocouple’s cold junction temperature value in degrees Celsius.
Serial.print("Reference temperature = ");
Serial.print(THERM.readReferenceTemperature());
Serial.println(" °C");
