Key Features

• Digital thermometer measures temperatures from -55°C to +100°C, typically in 0.2 seconds.
• Accuracy ±0.5°C within 0°C to +70°C.
• No calibration or reference required.
• Zero standby power.
• Power supplied throug
h data contact.
• Access to internal counters allows increased resolution through interpolation.
• Two bytes of EEPROM for use as alarm triggers or user memory.
• Built-in network controller.
• Alarm search directly identifies devices sensing alarming temperatures.
• Device-generated 8-bit CRC for on-the-fly data integrity check.
Common iButton Features

• Digital Identification and Information by Momentary Contact.
• Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code + 48-Bit Serial Number + 8-Bit CRC Tester) - Assures Absolute Traceability Because no Two Parts are alike.
• Multidrop Controller for 1-Wire Net.
• Chip-Based Data Carrier Compactly Stores Information.
• Data Can be Accessed While Affixed to Object.
• Button Shape is Self-Aligning with Cup-Shaped Probes.
• Durable Stainless Steel Case Engraved with Registration Number Withstands Harsh Environments.
• Easily Affixed with Self-Stick Adhesive Backing, Latched by its Flange, or Locked with a Ring Pressed Onto its Rim.
• Presence Detector Acknowledges When Reader First Applies Voltage.
• Meets UL#913 (4th Edit.). Intrinsically Safe Apparatus: Approved Under Entity Concept for Use in Class I, Division 1, Group A, B, C and D Locations (application pending).
The DS1920 provides direct-to-digital 9-bit temperature readings over a range of -55°C to +100°C in 0.5° increments. The iButton communicates with a processor using the 1-Wire protocol through a hardware port interface. The port interface provides both the physical link and handles the communication protocols that enable the processor to access iButton resources with simple commands. Two bytes of EEPROM can be used either to set alarm triggers or for storing user data. Armored in an iButton, the thermometer can measure temperatures in demanding environments. Like every other iButton, the DS1920 has a unique serial number. The 1-Wire interface reduces data output, address, and power to one line. A unique serial number allows multiple 1920s to share the same bus, with many sensors placed at different sites reporting to a single port on a processor. Multidropped DS1920s make the lowest-power temperature sensing network available inside buildings, equipment, or machinery and in process monitoring and control. With appropriate accessories the DS1920 easily attaches to an object or circuit board.
