DS18B20 1-Wire Digital Thermometers

Analog Devices DS18B20 Programmable Resolution 1-Wire Digital Thermometers provide 9-bit to 12-bit Celsius temperature measurements with a user-programmable alarm function for upper and lower trigger points. The DS18B20 devices feature a unique 1-wire interface that requires only one data line (and ground) for communication with a central microprocessor.
