Edu-Logger wide range temperature
logger sensor 900-244
The Edu-Logger wide range temperature sensor can be
used for any science experiment or activity 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 wide range temperature sensor over other
temperature sensors has its advantages:
Sensor accurately can measure between -200°C
and 1200°C –can be used in direct flames.
Extremely durable with a mesh metal wire
coating.
Hundreds of possible experimental subjects that can
be done with the 900-244 sensors are: exothermic and
endothermic chemical reactions, heat of combustion
for different materials, metabolism, heat and energy
transfer, effects of heat on enzyme function, weather
studies, material thermal conductance properties, and
many more.
The wide range temperature sensor uses the following
units of measure:
Celsius: The SI (International System of
Units) unit of temperature.

3
Fahrenheit: The temperature measurement
unit of the English System commonly used in
the United States.
Quick start procedure:
PC or Mac Computer
Materials needed:
900-244 Wide Range Temperature Sensor
900-213 USB Module
USB to mini USB cable (included with the 900-
213 module)
Your wide range temperature sensor needs to be
connected to a 900-213 module. The 900-213 module
then connects to a computer via a USB to mini-USB
cable. Please note that you cannot plug the wide range
temperature sensor directly into the computer.
Resident PC software and browser based application
can be downloaded for free at www.edulab.com 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 Edu-Logger software
2. Connect the 900-213 module to the PC or Mac
3. Connect the wide range temperature sensor to the
900-213 module (they directly plug together).
Please note that there is no calibration required
for this sensor.
4. Open the Edu-Logger software.
5. Once the wide range temperature sensor logo
appears on the left side of the screen the probe
has been automatically identified and you can
begin experimentation.

6. If the wide range temperature sensor is not
automatically identified then click the “Search
for sensors” icon to find the sensor.
7. Select the “On-line experiment” button; this will
open a graph below.
8. Click on the “Module setup” button located on
the wide range temperature sensor icon in the
module window to change the sensor 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 wide range temperature 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:
900-244 Wide Range Temperature Sensor
900-268 WiFi module
900-215 Battery
Your wide range temperature sensor needs to be
connected to a 900-268 module. The 900-268 module
will create a closed Edu-Logger WiFi network which
will stream the Edu-Logger data to a device of your
choosing. Once your device is wirelessly connected to
the Edu-Logger network you can run experiments and
collect data through a browser of your choosing.
Procedure:

5
1. Connect the wide range temperature sensor
directly to the left side 900-268 (no wires
required).
2. Connect a 900-215 module to the right side of the
900-268 module.
3. Although not required, we recommend plugging
the 900-215 to an outlet using a USB to mini
USB charger (such as a typical cell phone
charger). The 900-268 module will run for 15-75
minutes (depending on the sensor) without being
plugged in.
4. The 900-268 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 900-268 units with
the USB icon on the cover.
5. For further 900-268 instructions or the 900-268
quick start guide please visit: www.edulab.com
6. The 900-268 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 Edu-Logger network
which matches the 900-268 Module ID found on
the back of the 900-268 device. (Edu-
LoggerXXXX for example).
8. Give your device about 20 seconds to connect to
the 900-268.
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 wide range
temperature sensor. The icon will display real
time data.
14. Click on the “Module setup” button located on
the wide range temperature sensor icon in the
module window to change the wide range
temperature 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 900-268 (with the
USB icon on the cover) this can be used as a 900-
213, meaning you can tether the probes directly
to the computer using the 900-268. 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 Edu-Logger’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 Edu-Logger 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 at any time
using software.
The wide range temperature uses a thermocoupler to
accurately measure temperatures from very cold
(-200°C) to very hot (1200°C). Two wires of different
compositions and thermal conductance properties are
connected at the ends.
Because the metal wires have different properties both
heat and electricity are conducted at different rates.
Using the Seebeck Effect, a voltage is created in the
wires.
Different voltages are produced at different
temperatures. The voltage is what is directly
measured and then converted into a very accurate
temperature reading.
