The DS18B20 Digital Thermometer provides 9 to 12â€“bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of â€“55Â°C to +125Â°C and is accurate to Â±0.5Â°C over the range of â€“10Â°C to +85Â°C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power
Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1â€“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.
