Common Problem:

Q: What is the difference between PT100 and PT1000?

Answer: The PT100 reference resistor is 402R and the PT1000 reference resistor is 4.02K.

Q: What is the temperature measurement range:

A: The measurement range is -200-550 degrees Celsius. (See MAX31865 Specification Page 21)

Product Description:

MAX31865 AFE

High precision 0.1%/25ppm 402R reference resistor

Standard SPI interface, support SPI daisy chain for multi-channel temperature acquisition.

Support PT100/PT1000 two-wire, three-wire, four-wire mode, the default is 4-wire connection.

Provide STM32 demo program
- 1. Two-wire connection mode: Short-circuit A and B in the left picture and short-circuit on the right side of jumper C (factory default short-circuit on the right side).
  
  2, three-wire connection: A short, B disconnect, C short on the left, disconnected on the right.
  
  3. Four-wire connection mode: A disconnection, B disconnection, short-circuiting on the right side of C, and disconnection on the left side.
  
  4. D is the reference resistance and the resistance is 402R.
  
  5, the factory default is the four-wire sensor connection.
Package include:
