2. Connect the motion sensor to a USB-200 module (they directly plug
together). Please note there is no calibration required for this sensor.
3. Open the NeuLog software.
4. Click t he “Tools” icon.
5. Click “Restore sensor’s factory defaults” icon.
6. If prompted to clear the graph, click either the “Off-line experiment” or “On-
line experiment” (whichever you are using).
7. Click “Clear experiment results”.
8. Resume from step 4.

Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o C, o F, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.
For a deep theoretical discussion of how ultrasonic sonar motion detection systems
work please reference the American Association of Physics Teachers (AAPT) or The
Physics Teacher periodical.
The motion sensor emits an ultrasonic sound wave through the metal cone on top of
the sensor’s body. Sound waves follow a cone pattern and spread out at about 15°
around the point the metal cone is aiming at. Objects in the cone of detection reflect
the ultrasonic waves which are then detected by the sensor. Distance measurements
are measured rapidly and can easily be translated to velocity or acceleration also.
Maintenance and storage:
 Never submerge the NeuLog plastic body in any liquid.
 Do not allow liquid into the motion sensor’s body.
 After use, gently wipe away any foreign material from the motion sensor.
 Store in a box at room temperature out of direct sunlight.
