NEULOG ROTARY MOTION LOGGER SENSOR GUIDE
NeuLog rotary motion logger sensor
NUL-226
The NeuLog rotary motion sensor can be used for any science experiment
or activity which involves rotary motion including angular velocity, angular
acceleration, and revolutions per second such as in the fields of Mechanics,
Physics, Biomechanics, etc.
The sensor comes pre-calibrated so you can start experimentation right out
of the box using this guide.
Hundreds of possible experimental subjects that can be done with the NUL-
226 sensors are: rotary motion studies, angular velocity, angular
acceleration, sin waves, torque, engine studies, and many more.
The rotary motion sensor uses the following units of measure:
Degrees (°): The standard unit for measuring angles
Radians per second (rad/s): The angular displacement’s rate of
change.
Radians per second squared (rad/s2): The angular velocity’s rate of
change.
Revolutions per second (rev/s): The total number of complete
revolutions per second.
Using the rotary motion sensor:
The rotary motion sensor is can be set up in your classroom or lab in many
different configurations:
Connect the revolving head to a conveyor system.
Roll the revolving head along a surface.
Spin the revolving head manually.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-226 Rotary Motion Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your rotary motion sensor needs to be connected to a USB-200 module.
The USB-200 module then connects to a computer via a USB to mini-USB
cable. Please note that you cannot plug the rotary motion sensor directly
into the computer.
Resident PC software and browser based application can be downloaded for
free at
www.neulog.com/Download/SoftwareandApplication.aspx as well as a full
software user guide.
Note: Make sure not to download and install both types of software they
will conflict on the computer.

Procedure:
1. Install the NeuLog software
2. Connect the USB-200 module to the PC or Mac
3. Connect the rotary motion sensor to the USB-200 module (they
directly plug together). Please note there is no calibration required for
this sensor.
4. Open the NeuLog software.
5. Once a rotary motion sensor logo appears on the left side of the screen
the probe has been automatically identified and you can begin
experimentation.
6. If the rotary motion sensor is not automatically identified then click the
“Search for sensors” icon to find the sensor.
7. Select the “On-line experiment” button; this will open a graph below.
8. Click on the “Module setup” button located on the rotary motion
sensor icon in the module window to change the sensor settings if need
be.
9. Click on the "experiment set up" button to change the experiment
settings if need be (experiment duration for example).
10. The rotary motion sensor will give a live reading in the box to the left
of the screen while plugged in.
11. To run an experiment and collect data click “Run experiment”.
12. To end data collection early, click “Stop experiment”.
Tablet, smart phone device
Materials needed:
NUL-226 Rotary Motion Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your rotary motion sensor needs to be connected to a WIFI-201 module.
The WIFI-201 module will create a closed NeuLog WiFi network which
will stream the NeuLog data to a device of your choosing. Once your device
is wirelessly connected to the NeuLog network you can run experiments
and collect data through a browser of your choosing.
Procedure:
1. Connect the rotary motion sensor directly to the left side WIFI-201 (no
wires required).
2. Connect a BAT-200 module to the right side of the WIFI-201 module.
3. Although not required, we recommend plugging the BAT-200 to an
outlet using a USB to mini 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.
4. The WIFI-201 can be powered directly using a mini to USB cord and
plugging it into your computer or a wall charger. Please note this
function is only available on WIFI-201 units with the USB icon on the
cover.
5. For further WIFI-201 instructions or the WIFI-201 quick start guide
please visit:
www.neulog.com/Download/SoftwareandApplication.aspx
6. The WIFI-201 indicator lights will flash; take no action until the LED
to the far left turns blue; this can take up to one minute.
7. Take your tablet or smart phone, go to the WiFi settings and select the
Neulog network which matches the WIFI-201 Module ID found on the
back of the WIFI-201 device. (NeuLogXXXX for example).
8. Give your device about 20 seconds to connect to the WIFI-201.
9. Once the device is connected, go to your browser and type the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
10. You will see a “Control mode” icon in the browser, click on this icon.
11. The browser will then load a new screen and begin to auto detect the
sensor(s); this can take a minute. (You can stop the search when the
sensor is found.)
12. If the browser does not auto detect the sensor(s), select “Search for
sensors”.

13. Once the sensor is found you will see an icon on the left side of the
screen for the rotary motion sensor. The icon will display real time
data.
14. Click on the “Module setup” button located on the rotary motion
sensor icon in the module window to change the rotary motion probe
settings if need be.
15. Click on the experiment set up button to change the experiment
settings if need be (Experiment duration for example).
16. To run an experiment and collect data, select “On-Line” experiment,
then select "Run".
17. If you have a newer generation WIFI-201 (with the USB icon on the
cover) this can be used as a USB-200, meaning you can tether the
probes directly to the computer using the WIFI-201. To engage
operation in this fashion, press 3 times on the panel key. Repeating this
operation will return the unit to WiFi mode.

Materials needed:
NUL-226 Rotary Motion Sensor
VIEW-101 Viewing Module
BAT-200 Battery
Procedure:
1. Connect the rotary motion sensor to the left side of the viewer.
2. Connect the BAT-200 module to the right side of the viewer.
3. The VIEW-101 will auto detect the sensor and you will see it appear
on the left side of the screen.
4. Once the sensor appears it will be monitoring data in real time.
5. To run an experiment and collect data click the run button (little green
person).
Off-line experiments
(Off-line experiments are for when you do not have a sensor connected
directly to a computer, tablet, smartphone, or NeuLog viewer).

1. Connect the rotary motion sensor directly to the left side of a charged
BAT-200 module.
2. When ready to collect data press the “Start/Stop” button on the rotary
motion sensor, a red light will turn on for the duration of the
experiment.
3. To change the experiment settings first connect to your chosen device
(PC, Mac, tablet, smart device) and select the “Module setup” button.
(For more information on how to change the experiment settings view
quick start procedure section for your chosen device in this document.)

your chosen device. (full instructions in each device’s quick start
procedure section)
5. Open NeuLog software.
6. Click the “Off-line experiment” button.

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 at any time using software.
The probe shaft is installed in a bearing and has a magnet at its end. A
digital sensor based on Hall Effect sensor, analog circuit and a very
sophisticated digital processor is located near the rotating magnet.
The analog and digital circuits analyzes the rotating magnetic field and
calculates the angle, the rotation speed, acceleration and revolutions and
transfers this data to the sensor controller upon its request.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the rotary motion sensor’s body.
After use, gently wipe away any foreign material from the rotary motion
sensor.
Store in a box at room temperature out of direct sunlight.
