DS18B20 Water Proof Temperature Probe

This is the temperature sensor based on chip DS18B20 consisting of a waterproof probe and long wire shape, which is perfect for immersive temperature detection or detecting something far away. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) need to be connected from a central microprocessor.
