DESCRIPTION

• The MAX6675 is a precision digital thermocouple-to-SPI converter specifically designed for K-type thermocouples.
• Converts the tiny millivolt output of a thermocouple into stable, high-resolution digital temperature data.
• Features cold-junction compensation, automatically correcting errors caused by ambient temperature variations.
• Provides 12-bit digital output, enabling accurate high-temperature measurement.
• Consumes very low power (~50mW), making it suitable for battery-operated or embedded applications.
• Built-in noise filtering improves measurement stability, essential for industrial and lab environments.
• Available in a compact module with easy-to-use pins (VCC, GND, SCK, CS, SO) for rapid microcontroller interfacing.
• Offers seamless integration with Arduino, Raspberry Pi, ESP32, STM32, and other development platforms.
• Measures temperature from a single K-type thermocouple, ideal for focused monitoring tasks.
