The Adafruit MCP9600 I2C Thermocouple Amplifier handles all the analogue complexity of thermocouple measurement for you. Simply connect your thermocouple, wire up I2C, and read accurate temperature data from virtually any thermocouple type — K, J, T, N, S, E, B, and R types are all supported.

The MCP9600 includes built-in cold-junction compensation, configurable temperature alerts, and reports both the thermocouple (hot) and chip (cold) temperatures over I2C. The breakout board features a 3.3V regulator and level shifting, so it works with both 3.3V and 5V logic.

Key Features
