Adafruit MCP9600 I2C Thermocouple Amplifier

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9600 does all that for you, and can be easily interfaced with any microcontroller or single-board-computer with I2C. Inside, the chip handles all the analog stuff for you and can interface with just about any thermocouple type: K, J, T, N, S, E, B, and R type are all supported!

You can also set various alerts for over/under temperature and read the thermocouple (hot) temperature and the chip (cold) temperature. All this over common I2C. This breakout board has the chip itself, a 3.3V regulator and level shifting circuitry, all assembled and tested. Works great with 3.3V or 5V logic. Comes with a 2-pin terminal block for connecting to the thermocouple and pin header to plug into any breadboard or perfboard.

Match it up with our 1m K-type thermocouple. Works with any K, J, T, N, S, E, B, and R type thermocouple. Datasheet rated for K Type: -200°C to +1372°C, J Type: -150°C to +1200°C, T Type: -200°C to +400°C, N Type: -150°C to +1300°C, E Type: -200°C to +1000°C, S Type: +250°C to +1664°C, B Type: +1000°C to +1800°C, and R Type: +250°C to +1664°C.

Resolution of ±0.0625 °C - note that K thermocouples have about ±2°C to ±6°C accuracy. Internal temperature reading with 3.3 to 5v power supply and logic level compliant I2C data connection.
