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, highbandwidth 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 mobileelectronic devices such as cell phones and
iPods.

4. Samsung, 8.4MP CIS, September 8th, 2005
Sensor Size: 9×6.5 mm
Power consumption: 10 mW.
More importantly, the sensor’s output
is not an analog signal but a digital
signal.

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.
