(ISO9001-2008) Maxim/Dallas DS18b20 sensor

[Guangzhou] Posted Date: February 22, 2012

DS18B20 DIGITAL SENSOR :     Unique 1-Wire interface requires only  one port pin  for communication.   .  Multidrop capability  simplifies distributed  temperature sensing applications.   .  Require no external components.   . Can be powered from data line.    Power supply range is  3.0 V  to 5.5 V.   . Zero standby power required .   .  Measures  temperatures  from -55C   to  +125C.   Fahrenheit  equivalent  is -67F to  +257F.   . 0.5C accuracy  from -10C to +85C.   . 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 DS18B20.   . Alarm search command identifies and 8-Pin SOIC (150 mil) addresses devices whose temperature is outside of programmed limits (temperature PIN DESCRIPTION alarm condition) .   . Applications include thermostatic controls, DQ - Data In/Out industrial systems, consumer products, VDD - Power Supply Voltage thermometers, or any thermally sensitive NC - No Connect system   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   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 temperature inside buildings, equipment or machinery  and process monitoring and control.
