DS18S20 Dallas Digital Thermometer
DS18S20 Dallas 1-wire Digital Thermometer
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.
* Unique 1 Wire interface requires only one
port pin for communication
* Multidrop capability simplifies distributed
temperature sensing applications
