Vernier Go! Motion Sensor

1. The most frequently reported problems with a motion detector are 1 that the motion detector does not work beyond a certain distance or 2 that the graph is very noisy There are a number of ways to troubleshoot these situations and they are described below 1 See if the Sensitivity Switch makes a difference Simply set the Sensitivity Switch to the other position and retry the experiment This change may solve the problem 2 If Go Motion does not work beyond a certain distance e g it does not detect anything beyond 1 2 m here are some things to check e Check for movable objects textbooks ring stands etc in the cone of the ultrasound If possible move these objects out of the measurement cone It may not take a very large object to cause problems e Check for a stationary object chair table etc in the cone of the ultrasound This object may be detected when you are trying to study an object further away It may not take a very large object to cause problems If you have trouble with a stationary object causing unwanted echoes try setting the equipment up so that the objects are not in the cone or placing a cloth over the object This minimizes the ultrasound reflection e Also note that the cone of ultrasound extends downward from the center line This can cause problems if you are using Go Motion on a hard horizontal surface In these cases try pivoting the head of Go Motion to aim it slightly upward 3 No

7. isy or erratic data may have a number of causes Here are some tips e Sometimes other sound sources can cause problems If there is another source of ultrasonic waves in the same frequency range this will cause erroneous readings Examples include motors and fans air track blowers the sound made by the air exiting the holes on an air track etc Try to eliminate these sources of noise If you are using an air track try changing the air flow volume e Make sure that Go Motion is not placed close to a computer or computer monitor e If the room in which Go Motion is being used has a lot of hard sound reflecting surfaces you can get strange effects caused by the ultrasound bouncing around the room Standing waves can be set up between Go Motion and a sound reflector Try placing a cloth horizontally just in front of and below Go Motion This sometimes helps eliminate ultrasound that is skipping into Go Motion An excellent discussion of motion detector theory and operation can be found in Physics and Technical Characteristics of Ultrasonic Sonar Systems Dan MacIsaac and Ari Hamalainen The Physics Teacher 40 39 46 January 2002 e Try changing the data collection rate Sometimes Motion Detectors work better at Warranty one data rate than another Rates above 30 Hz do not work well in acoustically live rooms e If you are studying people moving have them hold a large flat object e g a large book or a pizza box a

11. uces a sufficiently strong echo Go Motion can pick up objects such as Sg Se chairs and tables in the cone of ultrasound The sensitivity of the echo detection circuitry automatically increases in steps every few milliseconds as the ultrasound travels out and back This change in sensitivity enables the detection of weaker signals ULTRASOUND MOTION DETECTOR Features of Go Motion e Go Motion is capable of measuring objects as close as 0 15 m and as far away as 6 m The short minimum target distance allows objects to get close to the detector which reduces stray reflections i Head e Go Motion has a pivoting head which helps you aim the sensor accurately For example if you want to measure the motion of a small toy car on an inclined plane you can lay Go Motion on its back and pivot Go Motion head so that it is perpendicular to the plane e Go Motion has a Sensitivity Switch which is located under the pivoting Go Motion head To access it simply rotate the detector head away from the detector body e Go Motion has automatic temperature correction allowing you to use it indoors at room temperature or outdoors at temperatures above or below room temperature e Rubber feet on Go Motion provide stability when it is placed on its back or standing up A standard camera screw mount can be found on the back of Go Motion This screw mount allows you to use the Motion Detector Clamp sold separately
