  • Measurement Range: 0 to 1024 deg C (32 deg F to 1875 F)
  • Measurement Resolution: +/- 0.25 Deg C (+/- 0.45 Deg F)
  • Output: Uses a SPI Interface
  • Sensor: Type K Thermocouple 

[Overview]
Thermocouples have been around forever and are a great way to measure temperature. They have a very large range, are robust and come in all kinds of lengths, varying tip configurations and a variety sheaths.

The challenge with using thermocouples is with the need for what is known as cold junction compensation and the need to detect a very small voltage change for every degree in change of temperature.

Fortunately there are chips like the MAX6675 that make connecting a thermocouple to your Arduino an affordable breeze. The device measures the output of a K Thermocouple and provides the result to the Arduino via a SPI interface.

[Specifications]

  • Supply Voltage: 3.3. to 5 VDC
  • Operating Current: about 50mA
  • Measurement Range: 0 to 1024 deg C (32 deg F to 1875 F)
  • Measurement Resolution: +/- 0.25 Deg C (+/- 0.45 Deg F)
  • Output: Uses a SPI Interface
  • Sensor: Type K Thermocouple 

[Pinout]

  • SO: The module’s serial output. Your Arduino will read this output.
  • CS: Chip Select. Setting low, selects the Module and tells it to supply an output that is synchronize with a clock
  • SCK : The Serial Clock… an input from your Arduino.
  • VCC: 5V supply
  • GND: Ground.
  • – (or Minus): The K thermocouple minus input.
  • + ( or Plus): The K Thermocouple plus input.
