Blinky-Max31865 System

The Blinky-Max31865 System is a precision 4 wire temperature measurement system based on the MAX31865 chip

Each module:

  • contains two channels with 15 bits of resolution.
  • is wireless and requires no communication cables.
  • is low power requiring a power source between 3.7 to 5.2V and draws a maximum current of 65mA
  • can be operated in pulse mode. The minium length of the current excitation pulse is 100 mS
  • packaged in a 4-mod wide DIN enclosure

The system allows the user to enter eighth order calibration curves for each temperature channel. The curves can be either a Taylor series expansion or a Chebyschev polynomial.
