The QS-M5B Microwave Motion Sensor is a highly efficient 5.8GHz radar-based automation device engineered for reliable motion detection in residential and commercial environments. Unlike traditional PIR sensors, its microwave technology can sense movement through non-metallic obstacles such as glass and thin partitions, ensuring broader and more accurate coverage. The unit supports both wall-mount (180°) and ceiling-mount (360°) installation, offering versatile placement based on your application. Adjustable detection range, sensitivity, ambient-light (LUX) settings, and time-delay control provide full customization for lighting automation. Designed for energy savings and hands-free operation, the QS-M5B is ideal for hallways, corridors, staircases, parking lots, and common areas where reliable, automatic lighting control is essential.
