The MAX6675 is a 12-bit resolution, SPI-compatible K-type thermocouple-to-digital converter module designed for accurate, high-temperature measurement. It combines a cold-junction compensation circuit, an amplifier, and an analog-to-digital converter, allowing microcontrollers like Arduino to read temperature data directly.�
The MAX6675 converts the small millivolt-level analog voltage produced by a K-type thermocouple (based on the Seebeck effect) into 12-bit digital data. It acts as an amplifier and analog-to-digital converter, making it ideal for industrial, appliance, or HVAC temperature monitoring applications. The module has pins for VCC, GND, and data lines, facilitating simple connection to microcontrollers.�
All the pins are clearly labeled as GND, VCC, D0, CS, CLK, , and – .
The two wires of the thermocouple come with the Red and Blue sleeves. Red is connected with the terminal of the max6675 module while the Blue wire is connected with the – terminal of the max6675 breakout module.
