7Semi MAX31855K K-Type Thermocouple Amplifier Breakout | SPI Temperature Sensor Module

The 7Semi MAX31855K K-Type Thermocouple Amplifier Breakout is a compact temperature sensing module designed for accurate digital temperature measurement in embedded, industrial, laboratory, and automation applications. Built around the MAX31855K thermocouple interface IC, the module converts thermocouple signals directly into digital data, eliminating the need for complex analog signal conditioning circuits and simplifying system integration.

The module communicates through a standard SPI interface, allowing seamless integration with Arduino, ESP32, STM32, Raspberry Pi, RP2040, and other microcontroller platforms. Integrated cold-junction compensation improves measurement accuracy by automatically compensating for ambient temperature variations, while built-in fault detection enhances system reliability.

Designed for reliable operation in embedded and industrial environments, the module supports temperature monitoring from -40°C to +80°C and is suitable for equipment monitoring, environmental sensing, process control, laboratory instrumentation, HVAC systems, and general-purpose temperature measurement applications.
