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 this guide.
Just a few of the thousands of possible experimental subjects that can be studied with
the NUL-202 sensor are: Van de Graaff generators, fuel cells, battery chemistry,
human muscle physiology, parallel circuits and series circuits.
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 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
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.
6. Take your tablet or smart phone, 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 about 20 seconds to connect to the WiFi-201.
8. 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.
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 sensor(s);
this can take a minute. (You can stop the search when the sensor is found.)
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 current sensor. The icon will display data in real time.
13. To set the current sensor’s settings, click on “Module setup” button located on
the current 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, select “On-Line” experiment, then select
"Run".
16. 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-202 Current Sensor
VIEW-101 Graphic Display Module
BAT-200 Battery Module
Procedure:
1. Connect the current 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).

1. Connect the current 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 current sensor,
a red light will turn on for the duration of the experiment.
3. To change the experiment 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 the experiment settings view the quick start
procedure section for your chosen device in this document.)
4. After the experiment has concluded (when the “Start/Stop” button is pressed
again or the data collection period ends) connect the sensor to your chosen
device (you can find full instructions in each device’s quick start procedure
section).

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.
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 use, gently wipe away any foreign material from the current sensor.
Store in a box at room temperature out of direct sunlight.
