NEULOG ACCELERATION LOGGER SENSOR GUIDE
NeuLog acceleration logger sensor
NUL-227
The NeuLog acceleration sensor can be used for any science experiment or
activity which utilizes acceleration measurements such as in the fields of
Physics, Mechanics, Physiology, Exercise Science, 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-
227 sensors are: gravitational force, impulse, exercise studies, human and
animal acceleration, and many more
The acceleration sensor uses the following units of measure:
Meters per second squared (m/s2): The SI unit of acceleration or
change in velocity over time.
Sensor orientation:
The NeuLog acceleration sensor has the ability to measure acceleration in
three different axes (X, Y, and Z). The figure below demonstrates the axes.
Note: You can also easily determine which axis is which by using this easy
method: First click on the sensor icon in the NeuLog software and select
the axis you wish to determine. Then change the physical orientation of the
acceleration sensor until the readout is roughly ± 9.8m/s2. When the sensor
reads roughly ±9.8m/s2, draw an imaginary line through the sensor towards
the ground, either end of the imaginary line (sky and ground) will be the
poles of the axis in relation to the sensor you are trying to determine.
To view all axes simultaneously:
After collecting data:
1. Open the NeuLog software and connect the acceleration sensor using
any of the following guides.
2. Once the sensor has been detected, click on “Offline Experiment”
3. Click on the acceleration sensor icon on the left.
4. Click on the “Range” button and select an axis (X, Y, or Z).
5. Click “Load Experiment” located on the top of the screen.
6. Select which experiment you would like to upload so that the button
turns green, the default is “Newest” (“Newest” will select the most
recent data collection)
7. Click on “Load Experiments” which will load the data from your
chosen axis onto the graph.
8. Resume from step 3 to load the other axes on the same graph.

Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-227 Acceleration Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your acceleration 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 acceleration 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 acceleration 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 acceleration sensor logo appears on the left side of the screen
the probe has been automatically identified and you can begin
experimentation.
6. If the acceleration 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 acceleration 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 acceleration 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-227 Acceleration Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your acceleration 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 acceleration 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

NEULOG ACCELERATION LOGGER SENSOR GUIDE
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 acceleration sensor. The icon will display real time data.
14. Click on the “Module setup” button located on the acceleration sensor
icon in the module window to change the acceleration 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.

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).

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 acceleration IC sensor houses three small thin silicon accelerometers.
Each accelerometer is oriented along a different axis (X, Y, or Z) connected
to a weight and based on piezoresistive technology. When an accelerometer
experiences acceleration along its axis the silicon will change it resistance
proportional to the acceleration it is experiencing.
This resistor changes are converted into voltage with Wheatstone bridge
circuit and read by the IC internal controller. The IC transmit upon request
the 3D accelerations in a digital form.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the acceleration sensor’s body.
After use, gently wipe away any foreign material from the
acceleration sensor.
Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and
workmanship for a period of 3 years from the date of purchase. Our
warranty does not cover damage of the product caused by improper use,
abuse, or incorrect storage. Sensors with a shelf life such as ion selective
proves have a warranty of 1 year. Should you need to act upon the warranty
please contact your distributor. Your sensor will be repaired or replaced.
Thank you for using NeuLog!
