DS18B20 Digital Temperature Sensor

Probe DS18B20 temperature sensor chip using original
After rigorous testing each probe individually wrapped
3.0V ~ 5.5V power supply
9 to 12 adjustable resolution
Temperature range -55 ° ~ +125 °
No external components , the unique single- bus interface
Output leads : Red (VCC), yellow (DATA), black (GND)


FEATURES
Unique 1-Wire interface requires only one
port pin for communication
Multidrop capability simplifies distributed
temperature sensing applications
Requires no external components
Can be powered from data line. Power supply range is 3.0V to 5.5V
 Zero standby power required
 Measures temperatures from -55°C to
+125°C. Fahrenheit equivalent is -67°F to
+257°F
±0.5°C accuracy from -10°C to +85°C
Thermometer resolution is programmable
from 9 to 12 bits
Converts 12-bit temperature to digital word in
750 ms (max.)
User-definable, nonvolatile temperature alarm
settings
Alarm search command identifies and
addresses devices whose temperature is
outside of programmed limits (temperature
alarm condition)
Applications include thermostatic controls,
industrial systems, consumer products,
thermometers, or any thermally sensitive system

DESCRIPTION

The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which
indicate the temperature of the device.
Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground)
needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and
performing temperature conversions can be derived from the data line itself with no need for an external
power source.
Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the
same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications
where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings,
equipment or machinery, and process monitoring and control
