Detects rapid light changes or light flashes.
Detects up to 1000 Lux (5.0 mW/cm2) within a 20°-wide cone field of view. Check the Light sensor for a wider field of view and larger illuminance detection range.
See this videoclip for a demo of the Flash applied together with the SeeLaser-Red !
Application examples
- Use for light source intensity measurement, map to a continuous controller and sweep your filters.
- Use with
SeeLaser-Red (red beam), SeeLaser-IR (invisible beam) or
SeeIR
(invisible beam, but for a distance less than 1 m) to create a break-beam that triggers when you cross it.
Laserharp anyone ? Create a virtual cage for dancers.
Or detect intruder, visitor, dog, cat, mouse .... movements.
- Combine with a
TapTiled floor,
some MoveOn
and/or ReachClose
sensors and make sure every move of your visitor has an effect.
