NEULOG CURRENT LOGGER SENSOR GUIDE
NeuLog current logger sensor
NUL-202
The NeuLog current sensor can be used for any science experiment which
utilizes current readings. It is used in the fields of Physics, Electronics,
Chemistry, Biology, etc.
The sensor comes pre-calibrated so you can start experimentation right out
of the box using any of the following guides.
Hundreds of possible experimental subjects that can be performed with the
NUL-202 sensor are: Fuel cells, battery chemistry, electrical parallel
circuits, electrical series circuits and electronics.
The current sensor's measurement units are:
Amperes (A): Amperes are the SI base unit of electric current.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-202 Current Sensor
USB-200 USB Module
USB to mini USB cable (which comes with the USB-200)
Your current 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 current 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 current 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 current sensor logo appears on the left side of the screen, the
probe has been automatically identified and you can begin
experimentation.
6. If the current 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 current 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 current 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-202 Current Sensor
WIFI-201 WiFi module
BAT-200 Battery Module
Your current 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 current 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 current sensor. The icon will display real time data.
14. Click on the “Module setup” button located on the current sensor icon
in the module window to change the current 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.

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 for free at any time using the provided firmware
update.
The NeuLog current sensor houses a shunt resistor and an amplifier. The
circuit's current passes through the shunt resistor and its electric potential is
measured using a very fast, high input impedance differential operational
amplifier with protected inputs. Using ohm’s law (I = V/R) the current is
calculated from the known resistance and voltage values.

NEULOG CURRENT LOGGER SENSOR GUIDE
The shunt resistor is very high power (to protect it in high current) and very
small resistance (in order not to affect the circuit conditions). The protection
is up to 5 A.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the current sensor’s 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.
