DESCRIPTION
   The DS18S20  digital  thermometer  provides  9-bit Celsius  temperature measurements and has an alarm function with nonvolatile user-programmable upper  and  lower  trigger points.  The  DS18S20  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 ±0.5°C over the range of –10°C to +85°C. In addition,  the  DS18S20  can  derive  power  directly  from the data line (“parasite power”), eliminating the need for an external power supply. Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus. Thus, it  is  simple to use one microprocessor to control many DS18S20s 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.
