سنسور دما DS1820

سنسور دما DS1820 یک دماسنج نسبتا دقیق برای کاربرد های عمومی ۵ ولت و با خطای حدودی ۰.۵ درجه و عدم حساسیت جدی به ولتاژ ورودی است.

FEATURES
• Unique 1–WireTM 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
• Zero standby power required
• Measures temperatures from –۵۵°C to +125°C in 0.5°C increments. Fahrenheit equivalent is –۶۷°F to +257°F in 0.9°F increments
• Temperature is read as a 9–bit digital value.
• Converts temperature to digital word in 200 ms (typ.)
• User–definable, nonvolatile temperature 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.
