This function converts the analog signal produced by a PT100 probe, connected via terminal blocks, into a digital signal that can be processed by a microcontroller. It is based on the MAX31865 chip.
- resolution of a few hundredths of a degree
- conversion rate of approximately 50 conversions per second
- SPI interface
- Liquid temperature measurement
- Air conditioning
- Temperature control
Adafruit have developed a library for the MAX31865, available in this GitHub repository.
- a terminal block is included, to which you can you can connect the output of a 3-wire PT100 probe (not included)
