Description 

The DS18S20 Digital thermometer provides 9-bit centigrade 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 -55C to +125C and is accurate to 0.5C over the range of -10C to +85C.   In addition, the DS18S20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
