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.
