The Motion Sensor and Data Studio 8/26/08 Sloane M. Schneider Lab Partners: Taylor Whipple, Cory Wilkinson, Amy Theory: The motion sensor used in this experiment emits multiple ultrasonic pulses in succession, at a rate determined by the person performing the experiment. The rate of collection general ranges between 10 and 50 Hz for the models used in this experiment. The pulses emitted reflect

off of any objects in its path and return back to the detector. The detector is connected to a computer which then uses a program that can precisely measure the time elapsed from the time the pulse was initially sent out to the time it returned and the reflected pulse was detected. From the 2008 Physics lab manual we see that the formula used for these calculations is: . Although the readings calculated by these devices are quite precise, they are very susceptible to error if the variables are not precise. When the distance to the object is either too small or too large the readings become inaccurate. Other things that may negatively affect the way the motion sensor performs include large particles floating around in the air, changes in the motion surrounding the object, and other motion sensors running nearby.
