IC DALLAS MAXIM DS18B20+ TO92

Temperaturni senzor MAXIM INTEGRATED / DALLAS DS18B20+,

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.
