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)

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

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.

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

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.
