Description

The RAK12022 is a PT100 sensor IO module that uses the MAX31965 resistance to digital converter. It is optimized for platinum resistance temperature detectors. The module supports 2-wire, 3-wire and 4-wire PT100 sensors and has an SPI interface. It extends the WisBlock temperature sensor series with an industrial temperature sensor.

We offer this module with an PT100 sensor, but if you want to use your own sensors, you can order the module without sensor as well.
