Thermocouple-to-digital converter module

Model: MAX6675.
MAX6675 K-Thermocouple-to-Digital Converter module can independently perform functions of signal amplification, cold-junction compensation, linearization, A/D conversion, and digital SPI Serial output.
MAX6675 is integrated with a cold-junction compensation circuit, with a simple 3-bit SPI-Compatible Serial Interface, digitalizing the signal from a type-K thermocouple and output in a 12-bit resolution. This converter resolves temperatures to 0.25, allowing readings as high as +1023.75. The operating temperature range is between -20~80.
