General Description
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius 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. In addition, the DS18B20 can derive power directly from the data line (“parasite power”),
eliminating the need for an external power supply. Each DS18B20 has a unique 64-bit 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.
