Class OneWireContainer22

  • All Implemented Interfaces:
    OneWireSensor, TemperatureContainer

    public class OneWireContainer22
    extends OneWireContainer28
    implements TemperatureContainer

    1-Wire container for temperature iButton which measures temperatures from -55@htmlonly °C @endhtmlonly to +125@htmlonly °C @endhtmlonly, DS1822. This container encapsulates the functionality of the iButton family type 22 (hex)


    • Measures temperatures from -55@htmlonly °C @endhtmlonly to +125@htmlonly °C @endhtmlonly. Fahrenheit equivalent is -67@htmlonly °F @endhtmlonly to +257@htmlonly °F @endhtmlonly
    • Power supply range is 3.0V to 5.5V
    • Zero standby power
    • +/- 2@htmlonly °C @endhtmlonly accuracy from -10@htmlonly °C @endhtmlonly to +85@htmlonly °C @endhtmlonly
    • Thermometer resolution programmable from 9 to 12 bits
    • Converts 12-bit temperature to digital word in 750 ms (max.)
    • User-definable, nonvolatile temperature alarm settings
    • Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
    • Software compatible with DS18B20 (family type 28 hex)


    See the usage example in TemperatureContainer for temperature specific operations.
