DESCRIPTION

UMW DS18B20

Stored in an On-Board ROM

. Multidrop Capability Simplifies Distributed

Temperature-Sensing Applications

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. It has

an operating temperature range of -55°C to +125°C

and is accurate to ±0.4°C over the range of -10°C to

+70°C. 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.
