How can you read temperature on a Raspberry Pi with no analog inputs? Today you will learn how to use OpenPLC's Python SubModule (PSM) to easily write hardware drivers to interface unsupported sensors with OpenPLC. On this video you will see a step-by-step example application adding support for the DS18B20 digital temperature sensor on a Raspberry Pi. Other sensors and hardware peripherals can be added using the same principles with PSM.
