Mounting Wireless Sensor
• Housed in a lightweight plastic enclosure – 3.125”x2”x0.875” weighing about one pound
• Two sensors comfortably
mounted above and below knee– Pouch and strap designed for
holding cell phones for
horseback riders

13Electrical and Computer Engineering
Processing and Display
• Counterpart XBee wireless receiver plugged into USB on BeagleBoard
• All data values plus timestamp logged into .txt file
• Python script on Beagleboard processes received sensor data• Real-time feedback
– Sends Arduino commands to interact with visual feedback– Playback of audio cues that were recorded by PT
• Data Logging– Stores all received data with single header
• Java GUI can plot and organize all of the logged data

15Electrical and Computer Engineering
PSFD : Input/Output
Python – Listen Script upon Beagle Startup
Arduino/BeagleBoard exchange simple serial messages
Audio feedback – limited use
7 Segment LEDs – low power, high visibility
