TheGrove - I2C Thermocouple Amplifier (MCP9600) is a thermocouple-to-digital converter with integrated cold-junction and I2C communication protocol. This module is designed to be used in conjunction with a k-type thermocouple. The thermocouples have a much larger measurement range than thermistors. For example, this k-type thermocouple on our shop can measure up to +500℃.
