Description
The MAX6675 is a digital thermocouple interface module designed for accurate high-temperature measurement using K-type thermocouples. It integrates cold-junction compensation and a precision amplifier, providing direct digital temperature output via SPI without requiring analog inputs. The module operates at 3.0–5.5 V and ensures stable performance across a wide temperature range. Its compact form factor and simple pin interface make it suitable for embedded systems and microcontroller-based projects. Ideal for industrial monitoring, laboratory experiments, and temperature control applications.
