OneWireSensor, TemperatureContainer

public class OneWireContainer22

extends OneWireContainer28

implements TemperatureContainer

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

Features

• Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F
• Power supply range is 3.0V to 5.5V
• Zero standby power
• +/- 2°C accuracy from -10°C to +85°C
• 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.
