NEULOG PHOTO GATE SENSOR GUIDE
NeuLog photo gate sensor
NUL-209
The NeuLog photo gate sensor can be used for any science experiment or
activity which involves taking accurate velocity and/or acceleration
measurements especially in the field of Physics.
The sensor comes pre-calibrated so you can start experimentation right out
of the box using any of the following guides.
Just a few of the thousands of possible experimental subjects that can be
done with the NUL-209 sensors are: velocity/acceleration/distance
relationships, impulse, collisions, conservation of energy, force,
momentum, and many more.
The photo gate sensor uses an infrared beam which detects if an object is
passing through it. Therefore the sensor actively reads out as “open” or
“blocked”. While collecting data however there are several parameters to
truly customize your experiment:
Velocity with a single gate
Velocity with two gates
Acceleration with a single gate
Acceleration with two gates
Change in time between two gates
Velocities with timing cards.
Experiment customization:
The NeuLog photo gate sensor offers several different experimental
customization options. To access them; click on the “Experiment Setup”
button after your photo gate sensor has been detected. Note: Refer to the
guides below for more information on using NeuLog sensors
Timing cards:
Making timing cards is a unique option to further customize any experiment
with the NeuLog photo gate sensor. To make timing cards we recommend
cutting your desired shapes out of black plastic for the most accurate
readings though even plain paper will work just fine.
For example:
Velocity with a single gate:
Velocity with a single gate is the very basic velocity measurement using
only one photo gate sensor and any object with a known width.
