Description
The MAX31855 K-Type Thermocouple Temperature Sensor Module is a digital temperature measurement module designed for high-temperature monitoring in electronics, industrial equipment, robotics, and DIY projects. It uses the MAX31855 thermocouple-to-digital converter IC to convert temperature readings from a compatible K-type thermocouple into digital data that can be read by a microcontroller.
Featuring built-in cold-junction compensation, a 14-bit temperature converter, and an SPI-compatible digital interface, this module makes it easy to integrate high-temperature sensing into Arduino, ESP32, Raspberry Pi, and other microcontroller-based projects.
With a listed measurement range of 0°C to 800°C, it is suitable for applications such as oven temperature monitoring, heating systems, hot-air equipment, temperature-controlled machinery, and educational electronics projects.
Key Features
- High-Temperature Measurement: Designed for temperature monitoring up to 800°C with the compatible probe supplied with the product.
- K-Type Thermocouple Support: Measures temperature using a standard K-type thermocouple.
- Digital Temperature Output: Provides digital readings through an SPI-compatible interface.
- 14-Bit Resolution: The MAX31855 converter provides a temperature resolution of 0.25°C.
- Cold-Junction Compensation: Compensates for the temperature at the thermocouple connection.
- Fault Detection: Supports detection of an open thermocouple and certain thermocouple short-circuit faults.
- Microcontroller Compatible: Suitable for Arduino, ESP32, ESP8266, and other SPI-capable controllers with appropriate voltage compatibility.
- Easy Integration: Ideal for prototyping, automation, monitoring, and temperature-control projects.
