Grove 1-Wire Thermocouple Amplifier (MAX31850K)

PRODUCT DETAILS

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.

Check out the Grove Selection Guide and hope to help you find the Grove suit you best.

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 Applications

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

Attention:

Usually the positive pole of the K-type thermocouple is red and the negative is light white, but we can't guarantee that all K-type thermocouples are like this. So the above diagram is only for the K-type thermocouple purchased from our website. If your K-type thermocouple is obtained from other places, you need to use other methods to judge the positive and negative.
