Examples of Sensor Systems
 Flight turbulence recorder
 Using 3-D accelerometer to take streaming data during
flight: turbulence = burst change in Y and Z axis speed
 Locate turbulence with Garmin GPS
 Using Matlab for data analysis

Examples of Sensor Systems
 Monitoring the T shuttles
 Is T-bus late again? Where is the bus right now?
 A sensor network could be used to detect bus location and
sync with back-end server

Examples of Sensor Systems
 Sensor tracking
 Track and locate stationary and moving objects
 Use location-aware sensor motes to determine distances
between motes
 Determine the location of a moving mote using
triangulation
