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 OutputExample

Wild Thingz Sensor Prototype Board #1

1. CodeBlocks IDE that utilizes JN5139 compiler to build a binary file

2. Jennic Libraries3. Flash programming GUI to get binary file on board4. USB to serial cable

Write Program

Build Binary File

Connect to camera via VCP

Erase Flash

Download binary file into flashDoug

Software Interface #1 Programming the boards

vJenie_CbInitSet up or connect to the wireless

network

vJenie_CbMainBasically an infinite for loop

vJenie_CbStackMgmtEventCalled when state of network has

changed

vJenie_CbStackDataEventCalled when data event has occurred

vJenie_CbHwEventCalled when on board hardware event has occurred

Doug

Code Layout

1. MATLAB will receive, process and send user data to the network.

2. USB to serial cable using a VCP driver3. MATLAB provides simple serial functions

1. Use for prototyping4. For demo – GUI that allows user to view network

data and change the behavior of the network5. Specific MATLAB functionality

1. Averaging of data from network1. Store most recent data2. Average older data

2. Image processing1. Conversion of data to .JPG

3. Display of network data4. Communication link between user and

network

Doug

Software Interface #2 Working with the network

s = serial('COM3') %s is the object (Jennic 5139)s.BaudRate = 19200 %set s to the correct baud ratefopen(s)i = 5j = 1while (j > 0) out = fscanf(s) if(out == 'Z') j = 10 break endendwhile (i > 3) data = fscanf(s) if(data == 'Z') break endend

Milestones

First Milestone• Initial prototype

– Motherboard– Sensor unit– Data processing and

human interface via MATLAB

– Wireless communication

Second Milestone• Final units

– Testing and debugging

– Fully functional sensor units (2) and motherboard

Demo• Fully functional wireless

sensor network• 2 sensor boards and 1

motherboard• GUI for human interaction

with network• Data display and ability

for user to modify network behavior

• Environmental model in lab• Demonstrates network

functionality
