The VMA324 ( DS18B20) Digital Thermometer provides 9 to 12bit (configurable) temperature readings which indicate the temperature of the device.

Features

• DS18B20 specs: unique 1wire interface requires only one port pin for communication
• Multidrop capability simplifies distributed temperature sensing applications
• Requires no external components
• can be powered from data line power supply range is 3.0 V to 5.5 V
• Zero standby power required
• measures temperatures from 55C to +125C (Fahrenheit equivalent 67F to +257F)
• 0.5C accuracy from 10C to +85C
• Thermometer resolution is programmable from 9 to 12 bits
• Converts 12bit temperature to digital word in 750 ms (max.)
• userdefinable nonvolatile temperature alarm settings
• Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
• 3wire adaptor for Arduino included
