Product details
Overview
UVIRSLIDER2EK from Silicon Laboratories is a demonstration kit implementing UV Index sensing, infrared touchless slider control, and ambient light measurement using the Si1146 optical sensor and C8051F800 microcontroller. It delivers real-time UV index output via five blue LEDs, supports left/right hand position tracking across eight LEDs, and detects swipe gestures with independent IR emitter activation (OSRAM SFH4056, 40 mW, 22° half-angle).
For engineers reviewing the UVIRSLIDER2EK datasheet, UVIRSLIDER2EK pinout, UVIRSLIDER2EK application, or UVIRSLIDER2EK equivalent, this board enables rapid validation of Si1146-based proximity, UV, and ALS functionality in human-interface and environmental monitoring designs - especially where gesture-aware UIs or sun-exposure safety feedback are required.
Technical Context
The UVIRSLIDER2EK Demo Board integrates the Si1146 optical sensor (U2) for UV/IR proximity/ALS measurements and the C8051F800 8-bit MCU (U1) for on-board firmware execution, gesture algorithm processing, and USB-to-I²C bridge functionality. All signal conditioning, IR emitter drive circuitry (DS1/DS2), and LED indication logic are implemented directly on the PCB.
It operates exclusively via USB bus power (5 V), uses pre-loaded firmware to drive real-time UV index display and IR slider response, and communicates with host PC software (UVIRSLIDER Demo, Si114x Programmer's Toolkit) through a virtual COM port interface emulating I²C over USB - no external programmer or debug probe required.

FAQ
What is the primary function of the UVIRSLIDER2EK?
The UVIRSLIDER2EK is a fully assembled demo board that demonstrates UV index measurement, infrared-based touchless slider positioning, and ambient light sensing using the Si1146 optical sensor and C8051F800 MCU. It ships with pre-loaded firmware enabling immediate operation via USB connection - no programming or configuration is needed to observe UV index LED output or hand-gesture responses. The UVIRSLIDER2EK serves as both an evaluation tool and reference design for integrating Si1146 into end products.
Does the UVIRSLIDER2EK require external power or programming to operate?
No - the UVIRSLIDER2EK receives all operating power (5 V) and communication capability through its onboard USB Type-A connector (P1). It boots automatically upon connection and runs pre-installed firmware that drives UV index LED patterns and IR slider behavior. No external power supply, JTAG debugger, or firmware flashing is required for basic operation. The UVIRSLIDER2EK is ready to use immediately after plugging into a standard USB port on a Windows PC.
Which software tools support the UVIRSLIDER2EK?
The UVIRSLIDER2EK is supported by three official Silicon Labs software packages: the UVIRSLIDER Demo application (GUI for UV index, IR slider, and UDP waveform visualization), the Si114x Programmer's Toolkit (API, command-line utilities, and sample source code for PC-hosted development), and the Silicon Labs IDE (for C8051F800 firmware development and in-system debugging). These tools enable full evaluation, customization, and migration of Si1146-based functionality - all compatible with the UVIRSLIDER2EK hardware interface.
Can the UVIRSLIDER2EK be used to develop custom firmware for the Si1146 sensor?
Yes - the UVIRSLIDER2EK includes the C8051F800 MCU with accessible debug headers and full USB-based programming support via the Silicon Labs IDE. Developers can modify or replace the factory firmware using provided example source code, adapt the Si1146 driver stack, and implement custom gesture algorithms or sensor fusion logic. The UVIRSLIDER2EK's schematic and API documentation allow direct register-level access to the Si1146 over the on-board I²C bus, making it suitable for production firmware development.
What are the physical dimensions and key components visible on the UVIRSLIDER2EK board?
The UVIRSLIDER2EK is a compact, single-sided PCB measuring approximately 70 mm × 40 mm, featuring the Si1146 sensor (U2), C8051F800 MCU (U1), two OSRAM SFH4056 IR emitters (DS1, DS2), five blue UV indicator LEDs, eight red/green signal LEDs for slider position, USB connector (P1), and discrete passive components for filtering and biasing. Component placement follows Silicon Labs' reference layout for optimal optical path integrity and EMI performance - visible in the official schematic (Rev. 0.1, Figure 3).
