NODE is a small wireless sensor that connects to iOS devices via Bluetooth 4.0, allowing 6 interchangeable sensor modules to detect properties like color, gases, motion, pressure, and temperature. It has a rechargeable battery, 3-axis sensors, and is compatible with iPhone 4S or newer as well as iPads and Macbooks. NODE is designed to enable app-based sensing and allow smartphones to access new sensor technologies.

3. INTRODUCTION
 NODE (wireless sensor)is a versatile
first-generation handheld sensor
measuring 1 inch in diameter and 3.75
inches wide that communicates
wirelessly through low
energy Bluetooth 4.0 with Apple
iOS devices.
Dr. George Yu

4. HARDWARE
•Arduino compatible
•Lithium Polymer battery (650 mAh)
•12-14 hours battery life with continuous Bluetooth
use
•2 MB memory
•3-axis accelerometer
•3-axis magnetometer
•3-axis gyroscope

5. APPS
NODE is an app driven product.
More than one app can use the NODE's functions to perform a
variety of tasks.

6. SENSOR MODULES
As of January 2013, 6
interchangeable sensor
modules were available , that
can detect: colour-CHROMA
gases-OXA
flash light-LUMA
barometric pressure-CLIMA
motion-KORE
surface temperature-THERMA

7. Highlights:
•9 degrees-of-freedom motion engine
•2 interchangeable module ports
•Open API with all modules
•long-range Bluetooth 4.0 Smart
Directly useful for:
•Motion mapping for animation or physical therapy
•Motion-based cues like telling when the washer
stops or the door opens
•Impact testing
•Use as a gesture-based remote control

8. Highlights:
•Measurement time: approx 1 second
• consistency : < 0.80deltaE reading to reading
consistency of the same color under same
temperature.
•Color information provided: CIE L*a*b*D65,sRGB
D65,HEX,CMYK,DeltaE 2000 for color comparision
Directly useful for:
•Ideal paint color matching and collecting module
•Quality
•Control
•Design

10. Highlights:
•Measure heat or cold at a distance
2 LED aiming guides
•Use the Therma App to mark heat signatures
Directly useful for:
•Inspecting heavy machinery at a distance
•Looking for weak points in insulation
•Testing for hotspots in walls
•Monitoring cooling systems
•Determining external food temperature
•Touchless thermometer

11. THERMA app

12. Highlights:
•Measures humidity, temperature, and barometric
pressure
•Senses ambient light
•Tells the climate of wherever you place it
Directly useful for:
•Testing humidity
•Monitoring for changes in temperature
•Light- or temperature-based cues
•Transmitting temp readings from firefighters in a
building to the fire chief outside

13. Highlights:
•8 High-brightness LEDs
•Use one or all of the 8 LEDs
•Extra-long sleep life via Bluetooth Low-energy
•Programmable flash patterns
•Adjust the lighting remotely from your Smartphone
Directly useful for:
•Compact flashlight for a car or bag
•Altering the mood-lighting right from your phone
•Remote signal lighting
•Turn on remotely during a power outage

14. Highlights:
•Stable electrochemical gas sensor for both
ambient and toxic level gas detection.
Used to detect and measure gases:
•Carbon Monoxide (0 - 400 ppm)
•Carbon Dioxide (500 ppm to 90%)
•Chlorine (0 - 10 ppm)
•Nitric Oxide (0 - 40 ppm)
•Hydrogen (0 - 20 ppm)
•Sulphur Dioxide (0 - 10 ppm)

15. COMPATIBLE DEVICES FOR BLUETOOTH 4.0
▪ iPhone 5
Mobile applications that ▪ iPhone 4S
display the data transmitted by
the NODE can be developed ▪ iPod Touch 5th Gen
thorough its open application
programming interface (API). ▪ iPad 3
▪ iPad 4
▪ iPad Mini
▪ Macbooks

16. CONCLUSION
NODE, a modular wireless sensor platform for
Smartphones that enables apps to access the
latest in sensing technologies.
This technology will completely
change the way people use their Smartphones
.Thus NODE, handheld powerhouse of sensors
is considered as the coolest gizmo of 2013.
