Description



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. For example, this k-type thermocouple on our website has a measurement range of -50℃ to +600℃.


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.


Again, this module can't work alone, it must work with a k-type thermocouple, if you do not have one, you can consider Thermocouple Temperature Sensor K Type-1M in our bazaar.


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.
