The sensors allow energy saving. When used in combination with 1-10V dimmable LED drivers or ballasts, the sensor can achieve 3-step dimming function, which is perfect for use in some areas that requires a light change notice before switching off. As it uses the third generation, technology, normal 5.8GHz microwave module can easily reach high mounting high up to 15m. Once any motion is detected by one of the sensors, the motion signal will be transmitted to other sensors connected together.
