NEULOG LIGHT LOGGER SENSOR GUIDE
4.
After the experiment has concluded (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).
5.
Open the NeuLog application.
6.
Click the “Off-line experiment” icon.
7.
Click the “Load data from sensors” icon.
8.
Select which experimental data to upload (5 experimental runs can be stored at
one time on the NUL-204 light sensor).
Restoring sensor’s factory default settings:
Procedure:
1.
Connect the USB-200 to a PC, Mac, tablet, or smart device.
2.
Connect the light sensor to a USB-200 module (they directly plug together).
3.
Open the NeuLog application.
4.
Click the “Tools” icon.
5.
Click the “Restore sensor’s factory defaults” on the menu.

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 (
o
C,
o
F, 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.
Inside the hard plastic casing, lies a photodiode which reacts with photons to release
free electrons (photoelectrons). The amount of light striking the sensor is directly
proportional to the voltage generated by the photoelectrons released. The sensor
measures the general voltage released and thus calculates the light intensity.
