Waterproof DS18B20 digital temperature sensor for Arduino is a waterproofed version of the DS18B20 temperature sensor. Handy for when users need to measure something far away or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so better to keep it under 100°C. The DS18B20 provides 9 to 12bit (configurable) temperature readings over a 1-wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor. Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery and process monitoring and control.
