MAX31865 PT100-PT1000 RTD Platinum Resistance Temperature Detector Module

The MAX31865 is an integrated circuit designed by Maxim Integrated for use with Platinum Resistance Temperature Detectors (RTDs), specifically PT100 and PT1000 sensors. These sensors are widely used in precision temperature measurement applications due to their accuracy, stability, and wide temperature range. The MAX31865 simplifies the process of interfacing these RTDs with a microcontroller by handling the signal conditioning and conversion tasks required to obtain accurate temperature readings.
