Title: A Survey on the Guinness Book of Sensors


1
A Survey on the Guinness Book of Sensors
  • Advanced Topics in Wireless Networks
  • Omar Amarin
  • 4/7/2008

2
  • Smallest Sensors
  • Epson, eCAM, Kionix, Samsung
  • Largest Deployment of Sensors
  • Department of Primary Industries (DPI)
  • Longest Lifetime Sensors
  • Transducer Technology, Inc.

Smallest Sensors
  • 1. Epson (uFR-II)
  • Advanced Model of World's Smallest Flying
    Microrobot from Epson (August 2004)
  • Micromechatronics technology
  • The world's new lightest and most advanced
    microrobot
  • The uFR-II is only the latest chapter in an Epson
    success story that began with Monsieur, a
    microrobot that was listed in the Guinness Book
    of Records as the world's smallest microrobot.

  • Problem Limited Range
  • Solution Fully wireless operation paired with
    independent flight capability. The world's
    smallest and lightest sensor.
  • Wireless features
  • - Epson's own sensor (world's smallest and
    lightest)

World's Smallest Gyro-Sensor (December 2004)
  • The XV-3500CB,
  • Characteristics
  • Features of the newly developed XV-3500CB
    Sensor
  • 1. Subminiature SMD
  • 2. Outstanding stability
  • 3. Sleep mode

4. Airtight structure

2. eCAM Ultra Compact, High Data-Rate Wireless
Sensor Node with a Miniature Camera
  • constructed by plugging a VGA video camera to the
    Eco node.
  • Eco is an ultra-compact, high-bandwidth wireless
    sensor node developed by authors. It measures
    only 13mm(L) 11mm(W) 7mm(H) and weights 2
    grams.
  • Great Power Consumption
  • Other Advantages

  • Some Properties
  • Ultra-Compact Form Factor 13x11x7mm, 2grams
  • 2.4GHz Radio, 128 Channels, 1Mbps
  • On-Board 3-Axis Accelerometer, Temperature
    Sensor,
  • Optical Sensor
  • Low Power Consumption
  • 40mAh Li-Polymer Rechargeable Battery, Continuous
    Listening about 4 hours
  • Flex-PCB Expansion Port Analog/Digital I/O, SPI,
    UART, I2C, and Interrupts,

3. Kionix, KXPS5, June 30, 2006
  • The device, the KXPS5, is just 0.9 millimeters
    thick, The sensor measures acceleration and is
  • primarily used for free-fall detection in
    hard drives.
  • The KXPS5 family of products was specifically
    engineered to have a very small form factor so
    that they can be incorporated directly into the
    hard disk drive.
  • use specifically in the hard drives of
    mobile-electronic devices such as cell phones and
    iPods.

  • How it works
  • Other Uses computer and video gaming, global
    positioning systems, sports diagnostics, and
    vehicle-stability applications.

4. Samsung, 8.4MP CIS, September 8th, 2005
Sensor Size 96.5 mm Power consumption 10
mW. More importantly, the sensors output is not
an analog signal but a digital signal. Micro
unit (MCU) Intelligent function

Ideas to Help in the Future
  • New custom printed circuit boards (PCBs)
  • Leads to (Risks)
  • Extra hardware development effort
  • Risking introduction of new errors

Largest Deployment of Sensors
World's Largest Agricultural Wireless Sensor
Network Department of Primary Industries (DPI)
  • Nectarine orchard covered with 47 nodes, 273
    sensors.
  • Sensors include soil moisture, soil and air
    temperature, canopy temperature, humidity, leaf
    wetness, trunk diameter, wind speed and
    direction, solar radiation and GPS co-ordinates.

  • Problems
  • 1. Interruptions
  • 2. Rainfall
  • Good Ideas They have started to monitor the
    sensor network using alerts that are
    automatically transmitted to a mobile phone by
    SMS.

Longest Lifetime Sensors
Transducer Technology, Inc.
D6F-P MEMS-based D6F-P air flow sensor
  • High performance
  • No recharge is required for more than a year.
  • Pocket CO
