Steinel 011727 DUAL-E KNX AP motion detector

The duality of light measurement. Regardless of whether it is a matter of directed or diffuse measurements, the Light Sensor Dual can do both! The challenge should not be underestimated. In order to obtain usable information about the lighting situation in a room, it is not enough to just determine the general brightness. It is important to combine the measurement, e.g. at table height, with the determination of the diffuse room brightness. This way, errors can be eliminated for better light control. And the STEINEL Light Sensor Dual is perfect for this.
