All Implemented Interfaces:

OneWireSensor, TemperatureContainer

public class OneWireContainer22
extends OneWireContainer28
implements TemperatureContainer

1-Wire container for temperature iButton which measures temperatures from -55@htmlonly &#176C @endhtmlonly to +125@htmlonly &#176C @endhtmlonly, DS1822. This container encapsulates the functionality of the iButton family type 22 (hex)

Features

• Measures temperatures from -55@htmlonly &#176C @endhtmlonly to +125@htmlonly &#176C @endhtmlonly. Fahrenheit equivalent is -67@htmlonly &#176F @endhtmlonly to +257@htmlonly &#176F @endhtmlonly
• Power supply range is 3.0V to 5.5V
• Zero standby power
• +/- 2@htmlonly &#176C @endhtmlonly accuracy from -10@htmlonly &#176C @endhtmlonly to +85@htmlonly &#176C @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)

Usage

See the usage example in TemperatureContainer for temperature specific operations.
