This board can be ordered as part number "115xOPT-EXP-EVB". The optical sensor expansion board is designed to allow customers to evaluate the Si1133 UV/ALS sensor
and other Si115x series sensors. A list of these sensors and their capabilities follows:
• UV/ALS—Si1133 sensor mounted with a demonstration light diffuser assembly.
• Long Range Proximity—Si1153-AB09 2 x 2 mm proximity sensing chip with an ondie 940 nm bandpass filter for sunlight immunity. The board demonstrates the use of
a 5 mm dia. lens and narrow-angle LED.
• Sunlight Immune Proximity Module—Si1153-AB9X, 2.85 x 4.9 mm proximity sensing module with an on-die 940 nm bandpass filter for sunlight immunity and an integrated 940 nm LED.
• Proximity/ALS—Si1153-AB00, 2 x 2 mm light sensor chip. The board uses a single
850 nm LED for demonstration purposes.
• Gesture/ALS—Si1153-AB00, 2 x 2 mm light sensor chip. The board uses three 850
nm LEDs spaced roughly 50 mm apart for demonstration purposes.

The optical sensor expansion board is designed to allow customers to connect to the
sensors using two methods:
• Silicon Labs EFM series of EVBs with an expansion ports. e.g. the EFM32 Pearl
Gecko PG12 Starter Kit: EFM32PG12 (SLSTK3402A)
• USB connectivity via the Optical Sensors Programmers Toolkit

2.1 SW1 Switch Configuration
es
ig
ns
It is important to note that only one of the sensors can be used at a time. That means only one of the eight switches in SW1 should be
moved to the right (the ON position) at a time. Each of the first five switches selects a different sensor on the board. The sixth position
selects a prototype area, the seventh selects an external expansion connector compatible with the Silicon Labs postage stamp boards
while the last is not used.
It is important to note that whenever the user wants to switch between sensors the board must be reset and the software restarted. This
is because only the SDA SCL line is switched by SW1 and a sensor that has set up could be generating interrupts when you want to
switch to another sensor.

2.3 Installation and Use of the Optical Programmer's Toolkit
Go to the Silicon Labs website, search for the Si1153 part and then download and install Rev 4.0 (or higher) of the Si1153/Si1133 Optical Sensors Expansion Board GUI from the Technical Resources section.

Note: In some installations, the application will not launch from the desktop icon of the Start menu but will launch from a windows explorer browser launching the executable, which is typically: C:\SiliconLabs\Optical_Sensors\Si115x\executable\launcher\Si115x
GUI.exe.
Figure 2.2. Main Panel of the Si1153/Si1133 Optical Sensors Expansion Board GUI
om
After launch, select one of the demos types (UV and ALS Demo, for example) in the drop box available in the Si115x main tab, and
then select the si115x Control Panel tab to configure one or more of the six measurement channels inside the Si115x part that are
available to perform the required task. If the “Launch (any) Demo” button is pressed instead then the control panel is initialized to a
“canned” demo and the view is changed to the Waveform viewer.
ec
The si115x control panel is mostly organized in 6 rows and 12 columns. The individual rows correspond to the six measurement tasks
that can be programed to run autonomously inside the part. Each task is run periodically at the sample frequency shown at the top of
the dialog box. The information that you enter here is transferred to the Si115x part when the "Commit Settings View waveform" button
is pressed. You can alternately use a button in the dialog box to examine the register setting thus created in the form of C sample code
for sending the values over.
N
ot
R
The seven columns on the left let you set up the tasks with the measurement conditions while the next two columns show the mean and
standard deviation of the resulting measurement. The measurement conditions you can set up include the selection of which photodiode to use, the integration time, range, and the current in each of the three LEDs. The statistics are computed on a sliding window of
the data output on the sensor, which introduces delay during transient conditions. This is an artifact of the GUI software and not of the
sensor itself.
The final three columns allow you to enable some in part software accumulation of readings and right shifting to prevent overflow.
If you click on the “Commit settings View Waveform” button, the setup shown will be transferred to the part and you will be transferred
to the Waveform viewer tab.

The waveform viewer tab shows all channels selected to operate and allows the user to set the scaling manually or let it run automatically. See the figure below.
This figure shows one ALS (ambient light sensing) channel and one proximity channel. During the operating a hand was passed over
the board and ALS sensor output (red) dropped while the proximity sensor output (green) increased.

This viewer is very useful for evaluating how the part would behave in a real product and we urge customers to add their own overlays
or optics to this board and then use this application to see what kind of optical signal their system would see. The raw data recorded is
as shown below.

The Five Sensors on the EVB
3. The Five Sensors on the EVB
3.1 UV/ALS
The Si1133 is sensor is mounted with a demonstration Teflon light diffuser assembly. The diffuser holder is made from carbon filled
black material and has an 1.2 mm diameter opening for light to reach the sensor while the 0.1 mm thin Teflon diffuser is a 2.3 x 2.3 mm
square that covers that opening.
es
ig
ns
This 1.2 mm circle at the back of the diffuser is illuminated by sunlight from the top at all angles but this circle is only visible to the UV
sensor in the Si1133 package from a narrow angle of ±25 degrees.
This design approach is critical to the accuracy of the UV sensor and this sensor should not be used without a carefully positioned
diffuser that uses a similar approach. Alternate diffusers can be much larger as it's the angles that matter. For example, a 1.2 meter
diffuser can be used as long as it is 1 meter above the Si1133 sensor.
See the drawings below for construction details of the diffuser used in this EVB.

The Five Sensors on the EVB
3.2 Long Range Proximity
The Si1153-AB09 2 x 2 mm is a proximity sensing chip with an on-die 940 nm bandpass filter for sunlight immunity. The board demonstrates the use of a 5 mm diameter lens and narrow-angle LED.
The 940 nm filter on the die and external LED are selected to coincide with a dip in solar energy that occurs around 940 nm. One gets
the advantage of rejecting visible and IR light by a couple of orders of magnitude and operating in a safe area with minimal sun energy.

The lens mounted over the sensor is designed to give the sensor a roughly ±5 degree field of view. The same is true for the lensed LED
used on the EVB with this sensor.

Revision 0.3
es

February, 2019
• Changed the lens and holder over the sensor to a molded plastic version that is easier for customers to implement.
• Changed the Teflon diffuser holder placed over the UV sensor to a version that is molded and easier for customers to implement.
• Removed the upconverter circuit that created 5.0 V from 3.3 V for the LED (3.3 Volts is sufficient).
• Changed the Si115x part numbers to match the current firmware rev (e.g., Si1153-AB09 vs. the older Si1153-AA09).
