Smallest Sensors

• 1. Epson uFRII
• Advanced Model of Worlds Smallest Flying
  Microrobot from Epson August 2004
• Micromechatronics technology
• The worlds new lightest and most advanced
  microrobot
• The uFRII 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 worlds smallest microrobot.

• Problem Limited Range
• Solution Fully wireless operation paired with
  independent flight capability. The worlds
  smallest and lightest sensor.
• Wireless features
• Epsons own sensor worlds smallest and

2. eCAM Ultra Compact High DataRate Wireless
Sensor Node with a Miniature Camera

• constructed by plugging a VGA video camera to the
  Eco node.
• Eco is an ultracompact highbandwidth wireless
  sensor node developed by authors. It measures
  only 13mmL 11mmW 7mmH 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 freefall 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
  mobileelectronic devices such as cell phones and
  iPods.

Largest Deployment of Sensors
Worlds 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 coordinates.

• 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.
