Philips sensor ready system with SNS sensor，Motion sensing ，The detection area for the movement sensor can be roughly divided into two parts:Minor movement (person moving ≤ 0.9 m/s). Major movement (person moving ≥ 0.9 m/s).Daylight sensing，The light sensor measures the total amount of light in a circular field of ≈ 80% of the PIR detection area. The following aspects should be observed during installation: Minimum distance from the window ≥ 0.6 m.Prevent light reflections from outside entering the sensor (for example sunlight reflection on a car bonnet) as this will lead to incorrect light regulation. As a guideline the formula 0.72 x H can be used to calculate the minimum distance between the window and sensor whereby H is the height from the bottom of the window to the ceiling.Photosensor Spatial Response .Energy reporting ，Record the law of lighting energy consumption，Daylight harvest and space occupancy detection ，So as to optimize the energy.Lighting asset management,Optimization of remote lighting system to reduce operation cost,A perfect energy management solution for whole building.
