The Grove - 1-Wire Thermocouple Amplifier (MAX31850K) is a thermocouple-to-digital converter with 14-bit resolution and cold-junction compensation. This module is designed to be used in conjunction with a k-type thermocouple. The thermocouples have a much larger measurement range than thermistors.

This module is based on the MAX31850K, which integrates amplifier, ADC and 64-bit ROM. Thanks to the 64-bit ROM, each device has a unique 64-bit serial code, which allows multiple units to function on the same 1-Wire bus. Therefore, it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.

  • Integrated Cold-Junction Compensation
  • Wide Conversion Range: allow readings from -270℃ to +1768℃
  • 14-Bit, 0.25℃ Resolution
