What?
• Widlife monitoring system
– Use wireless sensor network to gather data about
wildlife behavior and patterns
Christopher
Why?
• Wild life research
Reduces cost
Better results
Less risky
• Environmental Impact studies
Development projects
Construction
Christopher
How?
• Movement/Motion
• Take photographs
• Temperature
• Humidity
• Light
• GPS, wind
• Perform simple data manipulation and interpretation.

Wild Thingz Sensor Prototype Board #1
Camera
• Connected to one of the UART's
@ 38,400 BPS.
• No send/receive data
acknowledgments
Light Sensor
• Not connected to a channel of the
A/D converter.
• On board 12 bit A/D converter.
• Connected to DIO pins of MCU,
get a clock signal from MCU.
• The 12 bit digital output
represents light intensity.
Temperature and humidity sensor
• Works like the light sensor.
• Onboard 14 bit A/D converter.
• The 14 bit digital output represents
temperature and humidity levels.
Motion sensor
• Output of the sensor is a square wave.
• Take photos only when animal’s motion has been
detected.
• MCU samples DIO pin connected to motion sensor at
frequent and regular intervals.
• Code algorithms after testing
 Reduce the possibility of taking false photos
 Less data processing
 Reduce power consumption
Motion Sensor Output
Example
Voltage on DIO pin
1 0 0 1 1 0 1 0 0 1 1 1 1
Blowing grass – don’t take a picture

Programming the boards
CodeBlocks IDE that utilizes JN5139 compiler to
build a binary file
Jennic Libraries
Flash programming GUI to get binary file on board
USB to serial cable

Code Layout
vJenie_CbInit
Set up or connect to the wireless
network
vJenie_CbMain
Basically an infinite for loop
vJenie_CbStackMgmtEvent
Called when state of network has
changed
vJenie_CbStackDataEvent
Called when data event has occurred
vJenie_CbHwEvent
Called when on board hardware event
has occurred

Working with the network
MATLAB will receive, process and send user data
to the network.
USB to serial cable using a VCP driver
MATLAB provides simple serial functions
1. Use for prototyping
For demo – GUI that allows user to view network
data and change the behavior of the network
Specific MATLAB functionality
1. Averaging of data from network
1. Store most recent data
2. Average older data
2. Image processing
1. Conversion of data to .JPG
3. Display of network data
4. Communication link between user and
network
MATLAB Script
Example
s = serial('COM3') %s is the object (Jennic 5139)
s.BaudRate = 19200 %set s to the correct baud rate
fopen(s)
i=5
j=1
while (j > 0)
out = fscanf(s)
if(out == 'Z')
j = 10
break
end
end
while (i > 3)
data = fscanf(s)
if(data == 'Z')
break
end
end
