== Summary ==
Maxim MAX31855 cold-junction compensated K-type thermocouple thermometer with SPI interface for precise high-temperature measurements.

== Description ==
The **MAX31855 Thermocouple Thermometer** measures temperature using K-type thermocouples with built-in cold-junction compensation and fault detection. It provides high-temperature measurements with SPI communication interface, supports both Celsius and Fahrenheit output, and features error detection for thermocouple faults including shorts and opens.
