In this example we take a look at the MAX6675 Cold-Junction-Compensated K-Thermocouple-to-Digital Converter The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI™-compatible, read-only format. This converter resolves temperatures …
