NeuLog motion logger sensor
NUL-213
The NeuLog motion sensor can be used for any science experiment or activity which
requires accurate distance, velocity, or acceleration readings such as in the fields of
Physics, Mechanics, Physiology, Biology, etc
The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides.
The motion sensor uses an ultrasonic transducer to both transmit an ultrasonic wave,
and to measure its echo return. Objects in the range of 0.15 to 6 meters can
accurately be measured to give distance, velocity, and acceleration readings using
this method.
Just a few of the thousands of possible experiments that can be done with the NUL213 sensors are: gravity experiments, ball drops, momentum, impulse, conservation of
energy, kinetic vs. potential energy, and many more.
The motion sensor can collect data using the following units of measure:

Meters (m): The SI distance unit

Meters/second (m/s): The SI velocity unit which measures the distance
traveled over time.

Meters/second2 (m/s2): The SI acceleration unit which measures the change
in velocity over time.
For best results:
The NUL-213 motion sensor has a working range between 0.15m and 6.0 meters,
results may be inconsistent outside of this range. Ultrasonic waves that are emitted
from the sensor and spread out in a cone pattern at about 15° around the point of
reference.

If possible, attach the sensor to something stable to avoid movements which can
give skewed readings.
If you get poor readings, another object in the foreground or background that is
within the cone that may be reflecting the ultrasonic waves to add noise to the
experiment.
Use objects which are at least 10cm x 10cm when tracking specific targets.
For smaller targets we recommend starting the object closer to the sensor, for
larger objects we recommend starting farther away.
When testing in areas with many hard surfaces; the waves may bounce around
and create extra noise for the detector. This can cause irregular graphs. To
reduce the noise level try covering some of the surrounding surfaces with a soft
material to dampen sound such as cloth or foam.
When using the motion sensor to detect an individual’s movements; trying
carrying the sensor instead of pointing the sensor at one self. For example to
measure a student’s velocities have them walk or run with the sensor while
pointing it at the wall.
Make sure your motion sensor is not mounted near a computer, monitor, or
television.
Sometimes other sources of sound (such as fans, motors, etc can affect results).
Try various sample rates until the cleanest data is observed, slow rates may
provide better results for certain experiments.
Distance, velocity, and acceleration graphs:
During motion experiments it is often beneficial to show distance, velocity, and
acceleration all on the same graph. Using the NeuLog software it is very easy to plot
all three graphs at once:

Install the NeuLog software
Connect the USB-200 module to the PC or Mac
Connect the motion sensor to the USB-200 module (they directly plug
together). Please note there is no calibration required for this sensor.
Open the NeuLog software.
5.
Connect the motion sensor directly to the left side of a WIFI-201 module (no
wires required).
Connect a BAT-200 module to the right side of the WIFI-201 module.
Although not required, we recommend plugging the BAT-200 to an outlet
using a USB to micro USB charger (such as a typical cell phone charger).
The WIFI-201 module will run for 15-75 minutes (depending on the sensor)
without being plugged in.
For further WIFI-201 instructions or the WIFI-201 quick start guide please

The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.

Take your tablet or smart phone and go to the Wi-Fi settings and select the
NeuLog network which matches the WIFI module ID found on the back of
the WIFI-201 device. (NeuLogXXXX for example)
Give your device 1-2 minutes to connect to the WIFI-201 network.
Once the device is connected go to your browser and type in the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
You will see a “Control mode” icon in the browser, click on this icon.

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 (oC, oF, 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.

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.
