NEULOG GPS LOGGER SENSOR GUIDE
NeuLog GPS logger sensor
NUL-243
The NeuLog GPS (Global Positioning System) sensor can be used
for any science experiment which utilizes sensor readings in relation
to the location of each reading. It is mostly used in the fields of
Biology and Environmental science.
The sensor comes pre-calibrated so you can start experimentation
right out of the box using this guide.
Some of the hundreds of possible experimental subjects that can be
studied with the NUL-243 sensor are: Environmental monitoring
(weather, soil quality, water quality, and temperature), fitness testing,
and more!
The Global Positioning System (GPS) is a space-based satellite
navigation system that provides location and time information in all
weather conditions, anywhere on or near the Earth where there is an
unobstructed line of sight to four or more GPS satellites.
The GPS sensor's measurement units are:
Location in latitude and longitude data
Altitude in m.
Also, the sensor can be used as a USB module and can be
connected directly to the PC for configuring it and other sensors
connected to it.
The data from the sensors can be uploaded into the NeuLog
software.
With the NeuLog software data from the sensors connected to the
GPS sensor can be analyzed. The software can also export the GPS
data to Google Earth so the measurements and their locations can
be displayed together.
The NeuLog software is used after an experiment is carried out in
off-line mode.
Off-line experiments
(Off-line experiments are when you do not have a sensor connected
directly to a computer, tablet, smartphone, or NeuLog viewer).
Materials needed:
NUL-243 GPS Sensor
BAT-200 Battery Module
Any NeuLog sensor other than NUL-209 (photo gate sensor)
Materials needed to configure your offline experiment:
USB to mini USB cable (included with the USB-200 module)
Procedure:
1. Go outside where the GPS sensor can receive the satellites'
signals.
2. Connect the GPS sensor to a charged battery module and
(optional) to any other sensor(s).
3. When connecting the battery, the GPS sensor will flash once
with a red LED and three times with a blue LED. Any connected
sensors' red LED will flash three times.

NEULOG GPS LOGGER SENSOR GUIDE
4. After three seconds, the red LED on the GPS module will flash
three times. This means that the GPS sensor is OK and ready
for use.
5. Press the blue “start/stop” button on the front of the GPS sensor
for roughly a second.
6. The red LED indicator light will turn on until connection with the
satellites is made; this can take a few minutes.
7. When there is no satellite reception, the red LED on the GPS
sensor will remain on constantly.
8. If there is satellite reception, the red LED on the GPS sensor will
flash every second.
9. After the GPS sensor has been synchronized with the satellites,
the GPS sensor and any other connected sensor will take
measurements every 10 seconds.
10. When you are done collecting data, press the blue “start/stop”
button on the front of the GPS sensor for a second to end
measurements.
11. If the GPS sensor’s red LED changes from blinking every
second to being constantly on, this means that the GPS sensor
has lost satellite reception. Any other connected NeuLog
sensors will continue taking measurements. The GPS sensor
will continue to try and resynchronize with the satellites.
12. If the red LED on the GPS sensor and the other sensors blinks
rapidly, it means that the battery's power is low and it will soon
shut off (all data will be stored in the internal memory of the
sensors).
13. When the battery shuts off, no more measurements will be taken
by the GPS or any other sensor connected to it.
Quick start procedure:
PC Computer
Materials needed:
NUL-243 GPS Sensor
USB to mini USB cable (included with the GPS-243 module)
The software can be downloaded for free at www.NeuLog.com as
well as a full software user guide.
Choose "Downloads" on the main menu and then choose "Software
and Application".
Procedure:
1. Install the NeuLog software.
2. Connect the GPS module to the computer through the USB
cable.
3. (The GPS sensor functions as a USB module so make sure you
do not connect the GPS sensor to a USB module).
4. Make sure that the most current version of the Google Earth
software is installed on your computer.
5. You can download it from:
http://www.google.com/earth/download/ge/agree.html
6. Run the NeuLog software (version 3.63 or later).
7. After searching for sensors, make sure that you see a module
box for each of the connected NeuLog sensors on the left side
of the screen (including the GPS sensor).
8. On the main icon bar, click on the “Off-Line Experiment” icon.
9. On the sub-icon bar, click on the “Load data from sensors” icon.
10. A pop-up menu will open.
11. Click on the “All (last experiment) + GPS" option.

NEULOG GPS LOGGER SENSOR GUIDE
12. The NeuLog software will upload the collected data from any
connected NeuLog sensor first.
13. Then it will upload the GPS data.
14. When finished uploading the GPS data, the software will ask
you to save it as a “KML” file (Google Earth type).
15. The saved file will automatically open with Google Earth.
16. After running the Google Earth program, look for the “Places”
bar on the left.
17. There, you should find the file which you saved in the NeuLog
Program (GPS Sample).
18. Expand the file.
19. You should find:
a. Start position
b. Track
c. End position
d. Measurements for every sensor that was connected at the
time data was uploaded.
20. Sensors' measurements are shown as circles.

21. The color of the circle is changed from blue (for a low value
measurement) to red (for a high value measurement).
22. Clicking on a circle (in the map or at the bar on the left) will open
a balloon with the time (from the beginning of the experiment)
and the sensor’s measurement at that point.
