Edu-Logger RF communication module
900-216
The RF communication module allows for remote
operation of all Edu-Logger sensors. The RF modules
communicate wirelessly with one another –acting
similarly to a very long cable between the sensor and a
computer to stream data to the Edu-Logger software in
real time.
The working range of the RF module is up to 20
meters (65 feet) which adds a large amount of
flexibility to truly customize your experiments to your
specific needs.
The computer does not need to have Bluetooth or Wi-
Fi capabilities; everything required is built directly
into the RF communication module. The RF modules
will work with any computer which has a USB port to
connect the USB module into.

Using Edu-Logger RF modules:
As with all Edu-Logger devices, setting up the RF
communication modules is very quick and easy. It is
important however to follow these few steps to
properly collect data.
Materials needed:
2 RF communication modules (900-216)
USB module (900-213)
Battery module (900-215)
Any Edu-Logger sensor
Setting the RF ID number:
For your RF modules to properly work they must be
set to the same ID channel (paired) so they can
“speak”with one another directly. This is done very
easily using the Edu-Logger software. Keep in mind,
if you have multiple pairs of RF modules in the same
area they must be set to different RF ID values (1
through 9) to prevent interference.
1. Connect the USB module into your computer
using the included USB to micro-USB cable.
2. Connect both of the RF modules into the USB
module.
3. Open the Edu-Logger software.
4. Click on the “Edu-Logger Tools” button located
at the top of the screen.
5. In the dropdown menu click on “Set RF ID”.
6. Select an ID number (1 through 9) and make note
of your selection.
7. Note: To pair your RF modules, set the ID of
each RF to the same value (1 through 9).

8. Both of your RF communication modules are
now set to your chosen value (paired).
9. Note: This setup is not required prior to every
use as long as you keep modules with similar
ID’s paired for experimentation.
Connecting sensors using RF modules:
Once you have paired two RF communication
modules to the same RF ID number (1 through 9) you
can begin connecting Edu-Logger modules and
sensors together. Again it may be easiest to imagine
the RF communication modules as a long cable
between the sensor and the USB module.
1. Connect the USB module into a computer using
the included USB to mini USB cable.
2. Connect one of the paired RF modules to the left
side of the USB module.
3. Separately, connect the second RF module into
the left side of a charged battery module. Note:
press and hold the button on the front of the
battery module: if a light comes on, than the
battery has sufficient power. If no light comes
on, than you must charge the battery some more.
4. Connect whichever sensors you wish to use into
the left side of the second RF module (which is
connected into the battery). Note: You can
conduct experiments with up to 5 Edu-Logger
sensors using the RF modules.
5. Open the Edu-Logger software; it will
automatically search for sensors.
6. Once your sensors are detected you are ready to
begin collecting data wirelessly!
