The Mini-Proximity Demo provides a simple infrared proximity demonstration with the Si1102 infrared proximity sensor. The Si1102 controls an invisible infrared light emitting diode and senses an approaching object and illuminates a visible LED revealing the devices superior sensitivity and range. The coin-cell battery operated board enables demonstration under a variety of lighting conditions. For convenience, two thumb-wheel potentiometers provide an ability to set the sensitivity threshold to adjust for varying range requirements.
