NEULOG SURFACE TEMPERATURE LOGGER SENSOR GUIDE
NeuLog surface temperature logger sensor
NUL-233
The NeuLog surface temperature sensor can be used for any science experiment
which requires accurate temperature measurements such as in the fields of Physics,
Chemistry, Biology, Environmental Science, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using this guide.
Using the surface temperature over the standard temperature sensor has its
advantages:
It can be attached to surfaces easily with tape.
Its response time is faster due to the partially exposed thermistor.
It is more flexible and can fit into smaller areas.
A smaller surface area means you can accurately gauge the temperature of a
specific point instead of that of a larger area.
Among hundreds of possible experimental subjects that can be studied with the
NUL-233 sensor are: exothermic and endothermic chemical reactions, metabolism,
heat and energy transfer, human temperature changes, effects of heat on enzyme
function, weather studies, material thermal conductance properties, and many more.
This sensor is capable of measuring both in Celsius and Fahrenheit.
Celsius: The SI (International System of Units) unit of temperature.
Fahrenheit: The temperature measurement unit of the English System commonly used
in the United States.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-233 Surface Temperature Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your surface temperature 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 surface temperature sensor directly into the computer.
The browser based application can be downloaded for free at www.NeuLog.com as
well as a full application user guide.
Choose "Downloads" on the main menu and then choose "Software and Application".
Procedure:
1. Install the NeuLog application.
2. Connect the USB-200 module to the PC or Mac.
3. Connect the surface temperature sensor to the USB-200 module (they directly
plug together). Please note that there is no calibration required for this sensor.
4. Open the NeuLog application by clicking on the shortcut on the screen.
5. Once the surface temperature sensor module box appears on the left side of the
screen the probe has been automatically identified and you can begin
experimentation.
6. If the surface temperature sensor is not automatically identified, click the “Search
for sensors” icon to find the sensor.
7. Click on the “On-line experiment” icon; this will open a graph below.
8. Click on the “Module setup” button located in the surface temperature sensor
module box to change the sensor's settings if need be.
9. Click on the "Experiment set up" icon to change the experiment settings if need
be (experiment duration for example).
10. The surface temperature sensor will give a live reading in its module box to the
left of the screen while plugged in.
11. To run an experiment and collect data click the “Run experiment” icon.
12. To end data collection early, click the “Stop experiment” icon.
Tablet, smart phone device
Materials needed:
NUL-233 Surface Temperature Sensor
WIFI-201 WiFi Module
BAT-200 Battery Module
Your surface temperature 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.

NEULOG SURFACE TEMPERATURE LOGGER SENSOR GUIDE
Procedure:
1. Connect the surface temperature 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 60-90 minutes (depending on the sensor) without being
plugged in.
4. The WIFI-201 module 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 modules 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; Choose "Products" on the main menu,
then choose "WiFi Communication module".
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 (NeuLog0184 for example) which matches the ID found on the back of
the WIFI-201 module (0184 for example).
8. Give your device about 20 seconds to connect to the WIFI-201 module.
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 application, click on it.
11. The application 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 application does not auto detect the sensor(s), select “Search for sensors”.
13. Once the sensor is found you will see a module box on the left side of the screen
for the surface temperature sensor. In this box, real time data will be displayed.
14. Click on the “Module setup” button located in the surface temperature sensor
module box to change the surface temperature probe settings if need be.
15. Click on the “Experiment setup” icon to change the experiment settings if need
be (Experiment duration for example).
16. To run an experiment and collect data, click on the “On-Line experiment” icon,
then click the "Run experiment" icon.
17. If you have a newer generation WIFI-201 module (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 button. Repeating this operation will return the
module to WiFi mode.
Operation with NeuLog Graphic Display Module (viewer)

BAT-200 Battery Module
Procedure:
1. Connect the surface temperature 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, press the run icon (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).

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 surface temperature sensor uses a 10KΩ NTC thermistor (Negative Temperature
Coefficient variable resistor), which is a variable resistor that varies significantly with
temperature. The resistance increases nonlinearly with a decreasing temperature.
During calibration, the sensor’s internal controller creates the conversion formula from
resistance to temperature.
No calibration is needed ever for this sensor because the probe is permanently
connected to the controller and there is no need to change the conversion formula.

Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the surface temperature sensor’s body.
Do not use the probe in corrosive liquids.
After use, gently wipe away any foreign material from the surface temperature
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.
