DESCRIPTION
The DS18S20 Digital Thermometer provides 9–bit temperature readings which indicate the temperature
of the device.
Information is sent to/from the DS18S20 over a 1–Wire interface, so that only one wire (and ground)
needs to be connected from a central microprocessor to a DS18S20. 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 DS18S20 contains a unique silicon serial number, multiple DS18S20s 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.
