NEULOG PRESSURE SENSOR GUIDE
NeuLog pressure logger sensor
NUL-210
The NeuLog pressure sensor can be used for any science experiment or
activity which requires an accurate pressure measurement such as in the
fields of Physics, Biology, Physiology, Microbiology, Botany, Weather
Science, etc.
The sensor comes pre-calibrated so you can start experimentation right out
of the box using this guide.
Both the pressure and barometer sensors measure pressure however the
pressure sensor is much easier to connect to lab ware such as syringes,
beakers, and test tubes whereas the barometer sensor is ideal for testing
atmospheric pressure in the open or in large containers. A hose with an
attachment piece come connected to the sensor to make connections to
various mediums easier.
Hundreds of possible experiments that can be done with the NUL-210
sensors are: Boyle’s Law, Gay-Lussac’s Law for ideal gases, weather
phenomena, yeast and microbe fermentation, small animal exercise
physiology, chemical reactions, and many more.
The pressure sensor is capable of measuring in four different units of
measure:
Kilopascal (kPa): The SI unit of pressure.
Atmospheres (atm): A pressure unit equal to one earth atmosphere
at sea level (101.325 kPa)
Pounds per square inch (psi): The unit of pressure which measures
the amount of force (in pounds) a gas or liquid exerts across one
square inch
Bar: A non-SI unit equal to exactly 100 kPa
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-210 Pressure Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your pressure 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 pressure 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

NEULOG PRESSURE SENSOR GUIDE
3. Connect the pressure 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 pressure sensor logo appears on the left side of the screen, the
probe has been automatically identified and you can begin
experimentation.
6. If the pressure sensor is not automatically identified then 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 pressure 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 pressure 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-210 Pressure Sensor
WIFI-201 WiFi module
BAT-200 Battery
Your pressure 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 pressure 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.)
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 temperature sensor. The icon will display real time data.

14. Click on the “Module setup” button located on the temperature sensor
icon in the module window to change the temperature 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-210 Pressure Sensor
VIEW-101 Viewing Module
BAT-200 Battery
Procedure:
1. Connect the pressure 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).

Procedure:
1. Connect the pressure 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
pressure sensor; a red light will turn on for the duration of the
experiment.
3. To change the experiment's 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 experiment settings
view the quick start procedure section for your chosen device in this

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 pressure sensor uses the piezoresistive effect. The transducer is based
on silicon between metal foils that changes its resistance according to
pressure. One side of it is at complete vacuum that enables to measure the
absolute pressure on its other side.
This transducer is built as a strain gauge with Wheatstone bridge circuit so
its output is a voltage depends on it absolute pressure.
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.
