emits infrared light from the lower end to
detect objects such as fingers.
object passes through the area
illuminated by the infrared light source,
any infrared light reflecting off the object
is detected by the sensor.
To perform operation movement of
fingure neccessry.

No problem of detecting fingure while
infrared reflected wave in appropriate
amount
amount of reflected infrared light is too
high, the keystroke become too sensitive
or a “hovering” effect may occur.
Hovering: keystroke is recognized before
your finger touches the projection
surface.

1. Avoid direct sunlight.
2. Avoid low color temperature light
source, such as tungsten, halogen, or
incandescent lamp.
3. Avoid uneven or irregular surfaces.
Place the product on flat surfaces.
4. Avoid a table or surface that is as
transparent or reflective as glass or
mirror.
