This waterproof SMD DS18B20 temperature sensor provides 9-bits to 12-bit (configurable) temperature measurement and communicates over a 1-Wire bus that by definition requires only one data line for communication with a central microprocessor(Arduino). It is suitable for measuring surface temperature and offers steady performance even in wet conditions or at a far distance. Besides, the sensor comes with silicon lead wire, more temperature resistant than normal PVC materials. And they are digital, which means you don’t get any signal degradation even over long distances! Its operating voltage is 3 to 5.5 volts.

Each DS18B20 has a unique 64bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.

You can directly connect this sensor to an IO expansion board with our adapter(DFR0055), no soldering required.
