    This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

    Features:

    • Unique 1-Wire® interface requires only one port pin for communication
    • Each device has a unique 64-bit serial code stored in an onboard ROM
    • Multidrop capability simplifies distributed temperature sensing applications
    • Requires no external components
    • Can be powered from data line. Power supply range is 3.0V to 5.5V
    • Measures temperatures from –55°C to +125°C (–67°F to +257°F)
    • ±0.5°C accuracy from –10°C to +85°C
    • Thermometer resolution is user-selectable from 9 to 12 bits
    • Converts temperature to 12-bit digital word in 750ms (max.)
    • User-definable nonvolatile (NV) alarm settings
    • Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
    • Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
