1-Wire
SPECIAL FEATURES
? Digital thermometer measures temperature in
1/8°C increments with ±1°C accuracy
? Built-in real-time clock (RTC) and timer has
accuracy of ± 2 minutes per month from 0°C
to +45°C
? Water resistant or waterproof if placed inside
DS9107 iButton? capsule (Exceeds Water
Resistant 3 ATM requirements)
? Automatically wakes up and measures
temperature at user-programmable intervals
from 1 to 255 minutes
? Logs consecutive temperature measurements
in 2KB of datalog memory
? Records a long-term temperature histogram
with 1/2°C resolution
? Programmable temperature-high and
temperature-low alarm trip points
? Records up to 24 time stamps and durations
when temperature leaves the range specified
by the trip points
? 512 bytes of general-purpose battery-backed
SRAM
? Communicates to host with a single digital
signal at 15.4kbits or 125kbits per second
using 1-Wire? protocol
? Fixed range: H: +15 ° C to +46°C;
Z: -5 ° C to +26°C
COMMON iButton DEVICE
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
