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

Features

• DS18B20 specs: unique 1-wire 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 -55°C to +125°C (Fahrenheit equivalent -67°F to +257°F)
• ± 0.5°C accuracy from -10°C to +85°C
• Thermometer resolution is programmable from 9 to 12 bits
• Converts 12-bit temperature to digital word in 750 ms (max.)
• user-definable, non-volatile temperature alarm settings
• Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
• 3-wire adaptor for Arduino included
