LM34

Convert voltages measured with a thermocouple (LM34) connected to a LabJack U3 device into temperature units. Params: default : OrderedPair calibration1, calibration2, calibration3 : float Calibration parameters to convert voltage into temperature in Celsius. Returns: out : OrderedPair The output of the node is a list of temperatures measured from the sensors.
