This is the Arduino software library to access the Termopar Nanoshield, a thermocouple interface module using the MAX31856 IC from Maxim Integrated. It can read several types of thermocouples: K, J, N, R, S, T, E, and B.

• Source code: https://github.com/circuitar/Nanoshield_Termopar
• Documentation: http://nanoshield-termopar.readthedocs.org/
• Reference board: Termopar Nanoshield from Circuitar

Library features include:

• Get external temperature (hot junction)
• Get internal temperature (cold junction)
• Thermocouple type selection
• Continuous conversion mode
• Enable/disable averaging of 2, 4, 8 or 16 samples
• Error checking: open circuit, under/overvoltage and temperature out of range

To install, just click Download ZIP and install it using Sketch > Include Library... > Add .ZIP Library in the Arduino IDE.

The following examples are provided:

• SerialThermometer: simple serial port thermometer application.
• MultiThermometer: read temperature from multiple Termopar Nanoshields, with different thermocouple types.
• MultiThermometerCSV: read temperature from multiple Termopar Nanoshields, generating a CSV output.
• LcdThermometer: thermometer application using the LCD Nanoshield to display the data.
• RawVoltage: measure raw thermocouple voltage and cold junction temperature.
• TemperatureDatalogger: read temperature from multiple Termopar Nanoshields and log it into an SD card.
• OpenCircuitDetection: disable the open circuit detection mode or change its parameters. Might be useful when using long thermocouple wires.
