The Grove - 1-Wire Thermocouple Amplifier (MAX31850K) is a thermocouple-to-digital converters 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.

Features:

  • Integrated Cold-Junction Compensation
  • Wide Conversion Range: allow readings from -270℃ to +1768℃
  • 14-Bit, 0.25℃ Resolution
  • Will not work with any other kind of thermocouple except K type
  • Detects Thermocouple Shorts to GND or VDD
  • Detects Open Thermocouple

Typical Appilcations:

  • Medical
  • Appliances
  • Industrial
  • HVAC(Heating, Ventilation and Air Conditioning)

Technical Details:

  • Dimensions: 40mm x 20mm x 18mm
  • Weight: 4.90g
  • Operating Voltage: 3.3V / 5V
  • Temperature Resolution: 14 bits
  • Temperature Accuracy: ± 2℃
  • Operating Temperature Range: -40℃ to +125℃
  • Storage Temperature Range: -65℃ to +150℃
  • Allow Readings Range: -270℃ to +1768℃
  • Input Jack: DIP Female Blue-2Pin
  • Output Interface: 1-Wire bus
