Motion detector Light Sensor Dual - Steinel

The duality of light measurement.
Light measurement in perfection. The Light Sensor Dual photo-cell controller with KNX interface measures directed and diffuse light, watches over areas below the sensor and measures the room brightness. Combining the measurement results reduces error influences. Available either in round or square surface-mounted and concealed version.

No matter whether focused or diffuse measurements are needed - both work with the Light Sensor Dual! The challenge must not be underestimated. To obtain usable information on the lighting situation in a room, it is not sufficient simply to determine general brightness. It is important to use a combination of measuring the light level at the desk, for example, and determining diffuse room brightness. This way, errors can be ruled out for better lighting control. And the STEINEL Light Sensor Dual is simply perfect for this.
