MAX31855 Module +K Type Thermocouple Probe Sensor for Arduino Hot Competitive

About this deal

This MAX31855 module with K-type thermocouple probe is a compact breakout board designed for makers, hobbyists, and engineers who need to measure high temperatures with an Arduino or other microcontroller. The MAX31855 chip features a built-in 14-bit analogue-to-digital converter with cold junction compensation, and communicates via an SPI-compatible interface, making it straightforward to wire up alongside an external microcontroller. The board includes a 3.3V regulator with bypass capacitors and level shifting circuitry, all assembled and tested. The temperature measuring range is -200 degrees C to 1350 degrees C, with a resolution of 0.25 degrees C, and data is output as an SPI digital signal. For K-type thermocouples, accuracy is rated at plus or minus 2 degrees C across the range of -200 degrees C to +700 degrees C. Input voltage is 3 to 5V DC, and the module outputs a direct digital temperature value with no need for external amplifiers or an ADC. It suits applications such as kiln monitoring, cooking thermometers, industrial process control, and general electronics experimentation.
