Application examples

1. Measurement of proximity of people.
2. Combine with a TapTiled floor, some MoveOn and/or ReachClose sensors and make sure every move of your visitor has an effect. The Flash + SeeLaser combo adds a touch of diamond robbery feeling.

Application notes		Due to the modulation of the infra-red light that is used to detect a reflecting object the sensor is insensitive to ambient light variations. Glass or other transparent surfaces can be placed in front of the sensor but for best results place the sensor as close as possible to the surface and make sure the sensor emits/receives light perpendicular to the surface to avoid reflections that distort the sensor output. Warning ! Make sure the sensor is plugged into the Digitizer with the red wire connected to power.
