NEULOG PULSE SENSOR GUIDE
NeuLog Heart rate and pulse sensor
NUL-208 Carolina # 369637
The NeuLog pulse sensor can be used for any science experiment or activity which
requires a human heart rate or pulse such as in the fields of Biology, Health Sciences,
Physiology, Exercise Science, Psychophysiology, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides. Heart rate can be measured in two ways with this
sensor: in beats per minute or in analog arbitrary values to demonstrate the wave
signal of a heartbeat showing the blood volume in the finger or earlobe.
Just a few of the thousands of possible experiments that can be done with the NUL208 sensors are: physiological experimentation, relationship between heart rate and
oxygen flow, blood volume, psychological experiments which utilize heart rates, lie
detection, exercise experiments, VO2 max experiments, metabolism, and many more.
The heart rate and pulse sensor has two possible units of measurement:
Beats per minute: The amount of heart beats per minute
Arbitrary analog units: An arbitrary unit meant to show wave functions.
Probe usage:
The pulse probe uses plethysmograph based electrodes to record changes in blood
volume/flow. The sensor consists of an infrared LED transmitter and a matched
infrared phototransistor receiver.
For best results:
Wash hands before use.
Clip sensor to a fingertip or an earlobe.
Remain as still as possible until testing is complete
Nail polish can skew the results.
Let signal stabilize before reading.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-208 Heart Rate and Pulse Sensor
USB-200 USB Module
A USB to mini USB cable (which comes with the USB-200)
Your heart rate and pulse 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 heart rate and pulse sensor directly into the computer.
Resident PC software and browser based software can be downloaded for free at
www.NeuLog.com/dowload 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 heart rate and pulse 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 heart rate and pulse sensor logo appears on the left side of the
screen the probe has been automatically identified and you can begin
experimentation.
6. If the heart rate and pulse 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 heart rate and pulse
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 heart rate and pulse 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-208 Heart Rate and Pulse Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your heart rate and pulse 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 heart rate and pulse sensor directly to the left side of a WIFI201 module (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 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.
4. For further WIFI-201 instructions or the WIFI-201 quick start guide please
visit www.NeuLog.com/download.
5. The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.
6. 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)
7. Give your device 1-2 minutes to connect to the WIFI-201 network.
8. 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.
9. You will see a “Control mode” icon in the browser, click on this icon.
10. The browser will then load a new screen and begin to auto detect the
sensors, this can take a few minutes.
11. If the browser does not auto detect, select “Search for sensors”
12. Once the sensor is found you will see an icon on the left side of the screen
for the heart rate and pulse sensor. The icon will display data in real time.
13. To set the heart rate and pulse sensor’s settings click on “Module setup”
button located on the heart rate and pulse sensor icon on the left side of
your screen.
14. To change the experimental settings click the “Experiment setup” button
(experiment duration for example).
15. To run an experiment and collect data click “Run experiment”.
Operation with NeuLog viewer
Materials needed:
NUL-208 Heart Rate and Pulse Sensor
VIEW-101 Viewing Module
BAT-200 Battery
Procedure:
1. Connect the heart rate and pulse 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).
