MAX31855 K-Type Thermocouple Temperature Sensor Module

The MAX31855 K-Type Thermocouple Temperature Sensor Module is a high-precision temperature measurement module designed for use with Arduino, Raspberry Pi, ESP32, and other microcontrollers. It uses the MAX31855 cold-junction compensated thermocouple-to-digital converter, which provides accurate readings from a K-type thermocouple over a wide temperature range.

With built-in 14-bit resolution and SPI communication interface, this module delivers fast and reliable digital temperature data without requiring complex external circuitry. It is ideal for industrial monitoring, 3D printer hot ends, furnaces, kilns, ovens, and scientific experiments where accurate high-temperature measurement is required.
