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.

PACKAGE INCLUDES:
  • 1 × MAX6675 Module
