Miniature Microwave Motion Sensor Series - SenseMini SenseMiniTM Series - a miniature microwave motion sensor provides automatic control of lighting loads adding safety, values, convenience, and additional energy savings. Unlike Passive Infrared Sensor (PIR), it detects movement using a microwave sensor and turns the load on or dim1 the load to the preset dimming level providing sufficient safety or security while saving energy. In addition, the ambient light sensor is also integrated to determine the surrounding light situation and choose to activate or deactivate the motion sensor only when the illumination is needed. Using zero crossing triggered technology make sure the relay switch over when the AC load voltage at close to zero-phase, effectively extends the product’s life and safety to the user.
