MAX6675 K-Type Thermocouple Temperature Sensor Module | High-Precision 0-1024 °C Digital Temperature Module for Arduino & ESP32

Product Description

The MAX6675 Thermocouple Temperature Sensor Module is a precise and easy-to-use digital temperature sensing solution that combines a K-Type thermocouple probe with the MAX6675 cold-junction-compensated amplifier IC.

It accurately measures temperatures from 0 °C to 1024 °C and converts the readings into a 12-bit digital signal accessible through an SPI interface. This makes it ideal for Arduino, ESP32, Raspberry Pi, and other microcontroller projects requiring high-temperature measurement, such as industrial ovens, 3D printers, or heating systems.

Compact, reliable, and resistant to electrical noise, this module is widely used in automation, laboratory testing, and IoT temperature monitoring applications.
