DS1920-F5+

DS1920-F5+ is a digital thermometer (temperature iButton) that measures temperatures from -55°C to +100°C in typically 0.2s. 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 to store user data. It can measure temperatures in demanding environments. 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.

• 0.5°C resolution, digital temperature reading is two's complement of °C value
• Access to internal counters allows increased resolution through interpolation
• Reduces control, address, data, and power to a single data contact
• 8-bit device-generated CRC for data integrity, zero standby power
• 2bytes of EEPROM to be used Either as alarm triggers or user memory
• Alarm search directly indicates which device senses alarming temperatures
• F5 MicroCAN package
• Multidrop controller for MicroLAN, digital identification and information by momentary contact
• Data can be accessed while affixed to object
• Durable stainless steel case engraved with registration number withstands harsh environments
