MAX6675 K-Type Thermocouple Temperature Sensor Module

The MAX6675 Thermocouple Temperature Sensor 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.MAX6675 Thermocouple Temperature Sensor resolves temperatures to 0.25°C, allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8 LSBs for temperatures ranging from 0°C to +700°C. The MAX6675 is available in a small, 8-pin SO package. This is a commonly used module for temperature measurement. Though the supplier rating for the thermocouple is 80C, we have run them up to 150C with no issues noted.

This MAX6675 Thermocouple Temperature Sensor and module makes use of the Maxim MAX6675 K-Thermocouple to digital converter IC to provide a microcontroller compatible digital serial interface (SPI compatible) to provide accurate temperature compensated measurement of the supplied K-Type thermocouple sensor. It has a 12-bit resolution providing temperature readings from 0oC to 1024oC (max temperature of the supplied sensor is 450oC) with a resolution of 0.25oC
