NEULOG GALVANIC SKIN RESPONSE LOGGER SENSOR GUIDE
NeuLog galvanic skin response logger sensor NUL-217
The NeuLog GSR sensor can be used for any science experiment or activity
which utilizes the natural galvanic skin response (skin conductance) in the
fields of biology, physiology, psychology, etc.
Galvanic skin response, or skin conductance, is a measure of the changes in
the skin’s conductivity due to a stimulus, whether it is a picture, smell,
sound, touch, etc. Sweat glands are controlled by the sympathetic nervous
system which release small amounts of sweat when a stimulus is sensed.
This is how the GSR sensor can relate psycho-activity to sweat gland
activity.
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-
217 sensors are: physiological and psychological relationships and
responses to stimuli, human biology demonstrations, lie detection, and
many more.
The GSR sensor uses the following units of measure:
Micro Siemens (µS): A unit measuring electrical conductance.
Arbitrary analog units (Arb): An arbitrary unit to demonstrate
waves, frequencies, and periods.
Connecting to the GSR sensor:
The GSR sensor needs to form a strong connection to the skin in order to
work properly. For better results, the skin should be clean and wet.
Attached are two probes with Velcro finger connectors. While conducting
experiments, remain as still as possible for the best results.
1. Clean the bases of two fingers on the same hand with alcohol and wet
them a little with water.
2. Wrap the Velcro connectors around the two bases of the fingers,
securing as tightly as possible without causing discomfort.
3. For best results, ensure the flat metal piece on each Velcro connector is
located on the underside of each finger.
4. Attach both the white and the black snap connectors (located on the
end of the wire) to the Velcro finger connector by snapping to the
exposed metal nub.
Note: It does not matter which connector attaches to which finger.
5. You are now properly connected to the GSR sensor.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-217 GSR Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your GSR 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 GSR sensor directly into a computer.

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 GSR 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 GSR sensor logo appears on the left side of the screen the
probe has been automatically identified and you can begin
experimentation.
6. If the GSR sensor is not automatically identified then click the “Search
for sensors” icon to find the sensor.
7. Click on the “On-line experiment” button; this will open a graph
below.
8. Click on the “Module setup” button located on the GSR 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 GSR 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-217 GSR Sensor
WIFI-201 WiFi module
BAT-200 Battery
Your GSR 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 GSR 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:

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 GSR sensor. The icon will display real time data.
14. Click on the “Module setup” button located on the GSR sensor icon in
the module window to change the GSR 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.
Operation with NeuLog viewer
Materials needed:
NUL-217 GSR Sensor
VIEW-101 Graphic Display Module
BAT-200 Battery
Procedure:
1. Connect the GSR 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).

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 GSR sensor uses an internal very high impedance differential
operational amplifier to convert micro changes in the skins resistance and
conductivity into measurable voltage. This voltage is sampled by the sensor
controller.
When a stimulus is sensed, the sympathetic nervous system reacts causing
many physiological changes including releasing miniscule amounts of
sweat from sweat glands. These small changes of the skin’s moisture
change the skin and tissue conductance, which is measured by the sensor.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into either the GSR sensor or probes.
Wash hands prior to use for best results.
After use, gently wipe away any foreign material from the GSR sensor.
Store in a box at room temperature out of direct sunlight.
