MAX6675 Module with K Type Thermocouple Sensor

MAX6675 Module with K Type Thermocouple Sensor 

The MAX6675 Thermocouple Temperature Measurement Module is a high-accuracy digital temperature interface designed to work with K-type thermocouples. It converts the small analog voltage generated by the thermocouple into a stable, cold-junction-compensated 12-bit digital value, which can be easily read by microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, AVR, and others.

The module communicates through SPI (Serial Peripheral Interface) and provides reliable temperature readings from 0°C to 1024°C, making it ideal for industrial, high-heat, and scientific applications. The included K-type thermocouple probe allows measurement of high temperatures where normal sensors (NTC, thermistors, DHT11/22, DS18B20) cannot operate.
