SparkFun MIKROE THERMO Click

MIKROE THERMO Click features the MAX31855K thermocouple-to-digital converter as well as PCC-SMP connector for K-type thermocouple probes. The Click is designed to run on a 3.3V power supply. It communicates with the target MCU over an SPI interface (Read-only).

THERMO Click is a compact solution for adding thermocouple to your device.

The MAX31855 is a sophisticated thermocouple-to-digital converter with a built-in 14-bit analog-to-digital converter (ADC).

The MAX31855K has a temperature range between -270 and 1372�°C with sensitivity of about 41�¼V/�°C.

The device also contains cold-junction compensation sensing and correction, a digital controller, an SPI compatible interface, and associated control logic.

The combination of the MAX31855K and PCC-SMP connector results in support for high-accuracy temperature measurement.

In order to use THERMO Click you need to connect the appropriate K-type thermocouple probe (not included in the package) into the PCC-SMP connector.

The function of the thermocouple is to sense a difference in temperature between two ends of the thermocouple wires. The thermocouple�s �hot� junction can be read across the operating temperature range.

The reference junction, or â��coldâ�� end (which should be at the same temperature as the board on which the device is mounted) can range from -55�°C to +125�°C. While the temperature at the cold end fluctuates, the device continues to accurately sense the temperature difference at the opposite end.

Note: K-type thermocouple probe is not included in the package.
