    • The invention relates to a wireless sensor device configured for sensing motion of an object in an area. The device comprises a motion sensor configured for generating a sensing signal when sensing motion in the area and a signal processor configured for processing the sensing signal. A power supply is provided for providing power to the motion sensor. Furthermore, the wireless sensor device comprises a controller configured for distinguishing, from the sensing signal, large object movements and small object movements of the object in the area. The wireless sensor device is configured to perform one or more power consumption reduction operations upon detection of large object movement. The power consumption reduction operations include temporarily disconnecting the motion sensor from the power supply and decreasing a duty cycle of the signal processor.

    • An illumination system (10) comprises: —a light source (11); —a controller (12) controlling the power output of the light source; —a light sensor (16) wirelessly communicating with the controller. In a normal mode, the controller controls the light source such that the light level remains substantially constant. In a change mode, the controller controls the light source such that the light level is gradually changed with a predetermined change rate (R) such as to decrease a deviation from a target level (LT). The controller switches from its normalmode to its change mode on the basis of input signals received from the light sensor. The light sensor measures a light level, and decides whether or notto communicate a signalto the controller. The light sensor refrains from transmitting a signal when receiving the signal will not cause the controller to change its control behaviour.
    • 照明系统(10)包括: - 光源(11); - 控制器(12),控制光源的功率输出; - 与控制器无线通信的光传感器(16)。 在正常模式下,控制器控制光源,使得光级保持基本恒定。 在改变模式中,控制器控制光源,使得光水平以预定的变化率(R)逐渐变化,以减小与目标水平(LT)的偏差。 基于从光传感器接收的输入信号,控制器从其正常模式切换到其改变模式。 光传感器测量光电平,并决定是否将信号传达给控制器。 接收信号时,光传感器不发送信号,不会导致控制器改变其控制行为。

The controller is responsive to an input signal indicating a target color point (T) having target chromaticity coordinates (xT, yT) and target brightness (BT).

    • A wireless light sensor, being part of a lighting system, has a sensor element generating a light measuring signal, a microcontroller coupled to the sensor element, and a radio communication device coupled to the microcontroller. The microcontroller has an active mode and a sleeping mode. The light sensor further has a wake-up circuit which determines a rate of change of the light measuring signal, when the microcontroller is in the sleeping mode. The wake-up circuit brings the microcontroller from the sleeping mode into the active mode, when the rate of change of the light measuring signal exceeds a predetermined threshold.
