PT100 RTD Temperature Sensor Amplifier - MAX31865

To get precision and accuracy out of your PT100 RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires.

This RTD Sensor Amplifier with the MAX31865 breakout is for use with any 2, 3 or 4 wire PT100. The interface for the microcontroller is SPI.
