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.
- 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
- HVAC(Heating, Ventilation and Air Conditioning)
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.
