Advanced
Motion sensor
The
ScienceScope Advanced Motion sensor uses a combination of Infra-red and
Ultrasonic signals to accurately measure the distance between the transmitter
and the receiver. The unit can be set to provide a large range of distance range
outputs, velocity range outputs or acceleration range outputs. (See below)
As a result the unit can be used to
measure large changes in position or to measure tiny movements. In the highest
precision range for instance the resolution of the unit is approximately 0.03mm.
That is about the thickness of a human hair!
In order to maintain this level of
precision it is necessary for the unit to compensate for both for changes in
temperature and also humidity.
By using a novel technique to
measure distance this unit allows for a wide range of investigations to be
carried out that previously were not possible in the school laboratory.
