SparkFun Qwiic Thermocouple Amplifier - MCP9600 (Screw Terminals)

The SparkFun Qwiic Thermocouple Amplifier - MCP9600 (Screw Terminals) is a highly accurate device designed to measure temperature with precision. It's equipped with an I²C interface and two temperature sensors, one for the thermocouple and one for the chip. This enables the MCP9600 to read both the ambient temperature and the temperature of the object you're measuring with a resolution of 0.0625°C and an accuracy of ±1.5°C. The device is Qwiic compatible, which means it can be easily plugged in without any soldering, figuring out SDA or SCL, or voltage regulation.

The MCP9600 comes with screw terminals that allow you to hook up your own Thermocouple's wiring easily. This makes it ideal for a wide range of applications, whether you're checking the temperature of your slow cooker or ensuring your backyard induction furnace is at the correct heat.

The MCP9600 also features four on-board temperature alerts that can be configured according to your needs. Instead of constantly checking the sensor over I²C, you can set a temperature limit that triggers an interrupt when the temperature reaches a certain value. This leaves your microcontroller and I²C bus free to perform other tasks. The device also supports a burst mode for power saving, where it takes a specified number of samples, returns the results, and then goes to sleep. This low-power mode makes the MCP9600 perfect for portable applications.

SparkFun has developed an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun MCP9600' or you can get the GitHub repo as a .zip file and install the library from there.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Features of the MCP9600 include a temperature range of -200°C to 1350°C, four onboard temperature alerts, a resolution of 0.0625°C, a screw terminal connector, an ADDR jumper for variable I²C addresses (default address of 0x60), and 2x Qwiic connectors.
