This MAX31855 breakout board converts analog signals from K-type thermocouple into standard digital SPI data, supporting ultra-wide high-low temperature measurement. The internal cold junction compensation circuit effectively eliminates measurement errors caused by ambient temperature fluctuation. It can automatically detect abnormal states such as broken thermocouple wires for safer temperature monitoring. Widely applied in furnace temperature detection, industrial equipment thermal monitoring, 3D printer heating test and experimental electronic development. K-type thermocouple probe and main controller board are not included.
