Whether it's about directional or diffuse measurements, the Light Sensor Dual can handle both! The challenge should not be underestimated. To obtain usable information about the lighting situation in a room, it is not enough to simply measure the overall brightness. It is important to combine the measurement, for example, at table height with the determination of the diffuse room brightness. This way, error influences can be eliminated for better light control. And that's exactly what the STEINEL Light Sensor Dual is perfect for.
