UG163: Si1133/Si1153 Optical Sensor Evaluation Board User's Guide The optical sensor expansion board is designed to allow customers to evaluate the Si1133 UV/ALS sensor and other Si1153 sensors. A list of these sensors and their ca- pabilities follows:
- UV/ALS—Si1133 sensor mounted with a demonstration light diffuser assembly.
- Long Range Proximity—Si1153-AA09 2X2 mm proximity sensing chip with an on- die 940 nm bandpass filter for sunlight immunity. The Board demonstrates the use of a 5 mm dia. lens and arrow-angle LED.
- Sunlight Immune Proximity Module—Si1153-AA09, 2.85 x 4.9 mm proximity sens- ing module with an on-die 940 nm bandpass filter for sunlight immunity and an inte- grated 940 nm LED.
- Proximity/ALS—Si1153-AA00, 2 x 2 mm light sensor chip. The Board uses a single 850 nm LED for demonstration purposes.
- Gesture/ALS—Si1153-AA00, 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. EFM32WG-STK3800 (Wonder Gecko) or EFM32ZG-STK3200 Zero Gecko Starter Kits
- USB connectivity via the Optical Sensors Programmers Toolkit Note: Simplicity Studio sample code will be available in Q2 2016. KEY FEATURES

- Board Setup and Use
2.1 SW1 Switch Configuration
is important to note that only one of the sensors can be used at a time. That means only one of the 8 switches in SW1 should be moved to the left at a time. Each of the first 5 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 started. 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.
2.2 Board Setup for UV/ALS and the Optical Programmer's Toolkit
Figure 2.1. Board Setup for UV/ALS and Optical Programmer's Toolkit Using a USB Port UG163: Si1133/Si1153 Optical Sensor Evaluation Board User's Guide Board Setup and Use
2.3 Installation and Basic Use of the Optical Programmer's Toolkit
Download and install Rev 3.2 or higher of the Silicon Labs Optical Programmers toolkit. 2. Once installed, launch the application using: Start >> All Programs >> Silicon Labs >> Si114x Optical Sensor >> Launcher 3. Select UV and ALS Demo, and then click on the UV_ALS_DEMO button, as shown in the figures below. Figure 2.2.

2.4 Using the Si1150 Control Panel in the Programmer's Toolkit
Figure 2.4. Si1150 Control Panel in the Programmer's Toolkit The layout of the control panel mimics the programming registers described in the Datasheet. For example the parameter table allows the creation of up to six measurement tasks, each of which can be coupled to proximity ranging LEDs (or not). Each measurement task can be coupled to specific sensing photodiodes and associated integration time and range.
2.5 Simplicity Studio
Simplicity Studio will not include sample code to support the current evaluation board until Q2 2016. Users of this EVB can add their own code to Simplicity Studio projects. UG163: Si1133/Si1153 Optical Sensor Evaluation Board User's Guide Board Setup and Use
- The Five Sensors on the EVB
3.1 UV/ALS
Si1133 is sensor is mounted with a demonstration Teflon light diffuser assembly. The light opening behind the 1.6 mm diameter diffusor is a 0.8 mm diameter circle. The small size is preferred for the operation of the UV measurement and is an advantage for the customer. Figure 3.1. Teflon Diffuser UG163: Si1133/Si1153 Optical Sensor Evaluation Board User's Guide The Five Sensors on the EVB

3.2 Long Range Proximity
Si1153-AA09 2X2 mm proximity sensing chip with an on-die 940 nm bandpass filter for sunlight immunity. The Board demonstrates the use of a 5 mm dia. lens and arrow 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 is designed to give the sensor a roughly ±5 degree field of view and so is the lensed LED chosen and mounted next to it on the PCB. Figure 3.3.

3.3 Sunlight-Immune Proximity Module
A Si1153-AA09, 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 is mounted on the board. The 940 nm filter on the die and matching 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.
3.4 Proximity/ALS
The Si1153-AA00, 2X2 mm light sensor chip is mounted with a nearby 850 nm LED to demonstrate simple ALS and proximity measure- ments.
3.5 Gesture/ALS
The Si1153-AA00 2x2 mm light sensor chip is mounted on the board, while the PCB uses three carefully spaced 850 nm LEDs for to demonstrate gesture operation. UG163: Si1133/Si1153 Optical Sensor Evaluation Board User's Guide The Five Sensors on the EVB
