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.
