2. Introduction

The Si1120 Slider Demo Board implements an infrared touchless slider function based around the Si1120 infrared

proximity and ambient light sensor. As shown in Figure 1, the main components of the board are the Si1120 sensor

(U2), the C8051F930 microcontroller (U1), and two infrared emitters (D1 and D2). User feedback is provided by the

blue signal LEDs (DS0-DS7). Hardware is also provided on-board to facilitate code development for the

C8051F930 and communications with software support packages over a USB interface.

The firmware running on the C8051F930 measures the infrared light energy detected by the Si1120 while each of

the two infrared emitters are independently activated. The infrared light from these emitters will be reflected back to

the Si1120 by any object that is placed in proximity to the board. The left-right position is then calculated from these

two measurements, and used to illuminate the appropriate signal LED. If no object is close enough to the board,

the measured signal levels will fall below pre-determined thresholds, and no signal LEDs will be illuminated. In

addition to indicating the current position, the firmware is also able to detect different gestures from the infrared

sensor, as described in Table 1 on page 7. The Si1120’s ambient light sensor (ALS) is also monitored by the

firmware, which can determine the type of ambient light present.

Note: The touchless infrared position and gesture detection implemented in the example is patent pending.
