SparkFun Thermocouple Amp - Qwiic

The MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface, accessed over SparkFuns' Qwiic system. Inside the chip are two temperature sensors, one for the thermocouple itself (the hot junction) and one for the chip itself (the cold junction). As a result, the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure. The MCP9600 can do both with a resolution of 0.0625°C, and an accuracy of ±1.5°C (worst-case). Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required.

This version of the board comes equipped with a PCC connector to accept a K-type thermocouple. This makes it perfect for a variety of applications, from measuring the temperature of your Crock-Pot to making sure your backyard induction furnace is up to temperature.

In addition, the MCP9600 has four on-board temperature alerts that you can configure! Instead of constantly polling the sensor over I2C, you can set a temperature limit to trigger an interrupt when the temperature reaches a certain value. This frees up your microcontroller and your I2C bus to do more important things. It's also possible to put the MCP9600 into alternate operation modes in order to save power. The sensor supports a burst mode, where it will take a specified number of samples, return the results, and then go to sleep. This low-power mode makes the MCP9600 perfect for portable application.
