Adafruit Universal Thermocouple Amplifier MAX31856 Breakout

Key Features:

• Works with any K, J, N, R, S, T, E, or B type thermocouple
• -210°C to +1800°C output in 0.0078125 ° resolution - note that many thermocouples have about ± 2°C to ± 6°C accuracy or worse depending on the temperature and type
• Internal temperature reading
• 3.3 to 5v power supply and logic level compliant
• SPI data requires any 4 digital I/O pins

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we' ve suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we' re happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy!

This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple.

This breakout does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). We even added inline resistors and a filter capacitor on-board for better stability, as recommended by Maxim. Goes great with our 1m K-type thermocouple or any other thermocouple, really!
