MAX31865 is an easy to use RTD to digital converter. It is specially designed to work with PT100 and PT1000 temperature sensors with 2, 3 and 4 wire connection. The MAX31865 is essentially a 15 bit ADC (analog to digital converter) which guarantee accuracy measurements for PT100 and PT1000 resistance to digital temperature sensors. This module was tested and quality approved in Future Electronics Egypt Lab as shown in the video below.
