What is an iButton?
• ID/eCash token, Datalogger & Data carrier
– Smart IC chip inside a rugged stainless steel container
– Unique 64 bit Address for identification
– Stores information
• Varying memory capacity
• Various security protection mechanisms
• Record environmental conditions
– Simple 1-Wire® Touch Interface
– Minimum 10 year life span
iButton is a smart token, much more durable and versatile than a prox card!
Over 120 million iButtons have been shipped to customers worldwide!
6
What is an iButton?
• 64 Bit Unique and Unalterable Address
– Over 280 trillion available addresses
• Over 45,000 buttons per person
– Address is factory-lasered into chip and onto can
• 1-Wire Protocol
– Only 2 contacts needed for data transfer (DATA / GND)
– Multiple buttons on the same wire form a 1-Wire Net
• Very Rugged
– Stainless steel “can” protects the device
– Withstands harsh environments
• water, dirt, and chemicals
– Wide temp range (-40C to +85C, ds1922T to 125C)

Where are iButtons used?
8
iButton Applications...
• Guard Tour
– Keep track of your guard’s
inspections and what is
happening at your facility
9
iButton Applications...
• Electronic Change Purse
– Parking meters
– Gas purchases
10
iButton Applications...
• Fleet Management
– Maintenance
– User Authorization
– Vehicle Fueling
11
iButton Applications...
Time & Attendance
– Agricultural workers
use iButtons to track
the amount of work
completed
12
iButton Applications...
• Access Control
– iButtons can provide
secure access to many
devices such as PC’s,
Office Machines and
Vehicles.
13
iButton Applications...
• Access Control
– Many installations
utilize iButtons as
the electronic key
for access to
buildings, rooms,
storage areas,
restricted areas, etc
14
iButton Applications...
Prepay Utility Meters
iButtons are used as smallchange purse (token) for
buying water, gas, electricity,

– Serial interface for an analog-to-digital converter
(ADC)
– With an external ADC and charge pump, the DS2422
can be used for many data logging functions, such as
pressure monitoring, light sensor monitoring, logging
thermocouple temperatures, etc.
54
Determining the Best Mission Sample
Rate
Customer wants to monitor a shipment over 10
days.
The ds1921 captures 2048 samples.
So: 10 days/2048 samples = 7.03 min/sample
