Playing With Fusion MAX31865 Arduino Library

Arduino library designed to interface Arduino-compatible hardware with the Maximum MAX31865 RTD to digital converter IC over SPI, used for digitizing RTD measurements. Examples provided to interface with SEN-30201, FDQ-30002, and SEN-30202.

Library Documentation

Brief documentation for this library. Make sure to see "examples" folder for ready-to-upload programs.

Configuration

Configuration of a RTD requires the user to know:

• How many wires were used to wire the RTD

• The type of RTD (PT100 or PT1000)

A basic configuration for a PT100 RTD in 3-Wire configuration could look like this:

MAX31865 rtd;

void setup() {
  // Where "2" is the SPI chip select
  rtd.begin(2, RTD_3_WIRE, RTD_TYPE_PT100);
}

= SEN-30202: PT100 2-ch, PT1000 2-ch
