NEULOG PULSE SENSOR GUIDE
NeuLog heart rate and pulse logger sensor
NUL-208
The NeuLog pulse sensor can be used for any science experiment 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 this guide.
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.
Hundreds of possible experiments that can be performed with the NUL-208
sensor are: physiological experimentation, relationship between heart rate
and oxygen flow, blood volume, psychological experiments which utilize
heart rates, lie detection, exercise experiments, VO2max experiments and
metabolism.
The heart rate and pulse sensor has two possible units of measurement:
Beats Per Minute (BPM): The amount of heart beats per minute
Arbitrary analog units (Arb): An arbitrary unit meant to show wave
functions.
Probe usage:
The sensor consists of an infrared LED transmitter and a matched infrared
phototransistor receiver (light detector).
For best results:
Wash hands before use.
Clip sensor to the little finger (pinky) or earlobe.
For better results, place the light detector (has white transparent cover)
side of the clip on the pad of your finger, not the nail.
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
USB to mini USB cable (included with the USB-200 module)
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 application can be downloaded for
free at
www.neulog.com/Download/SoftwareandApplication.aspx as well as a full
software user guide.

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 no calibration is 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, click
the “Search for sensors” icon to find the sensor.
7. Click 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's 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 Module
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 the 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
WIFI-201 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 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.)

NEULOG PULSE SENSOR GUIDE
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 heart rate and pulse sensor. The icon will display data in
real time.
14. Click on the “Module setup” button located on the pulse sensor icon in
the module window to change the pulse 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 click “Run experiment”.
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-208 Heart Rate and Pulse Sensor
VIEW-101 Graphic Display Module
BAT-200 Battery Module
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).
Off-line experiments
(Off-line experiments are when you do not have a sensor connected directly
to a computer, tablet, smartphone, or NeuLog viewer).

NEULOG PULSE SENSOR GUIDE
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 pulse sensor’s probe consists of a fingertip/earlobe clip which houses
an infrared light source and an infrared light detector on opposite sides.
The blood in the finger flows forward (oxygenated with oxygen) and
backward (deoxygenated with CO2). The IR light absorbed by the
deoxygenated blood and the detected light intensity changes are according
to the heart pulses.
The light average intensity changes according to the skin color, thickness,
the probe pressure etc. The sensor electronics offsets the average intensity,
amplifies and passes the pulses only to the internal controller, which
calculates the pulses' rate.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the NeuLog plastic body.
After using the probe, wipe off all excess material, liquid or residue
from the 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. The warranty is for a period of 3 years from the date of
purchase and does not cover damage of the product caused by improper use,
abuse, or incorrect storage. Sensors with a shelf life such as ion selective
probes 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!
Flexible, simple, fast, forward thinking.
