Control Principle: Microwave sensors transmit and receive high-frequency microwave signals to accurately detect movement and object changes. A single-chip computer program amplifies the signal and performs intelligent identification to control the load lamp's switch function. This principle, similar to radar technology, is widely used in aviation, aerospace, and various industries. Smart Sensing: 1. When someone enters the detection area (within a 16m diameter), the load lamp turns on. When the person leaves, the set delay time countdown begins, and the load lamp automatically turns off. 2. If someone enters the detection area while the load lamp is already on, any slight movement (including limb movements) before the set delay time countdown ends will keep the sensor active, maintaining the load lamp's illumination until the person leaves and the countdown completes. The load lamp then automatically turns off. Intelligent Recognition: 1. This product can be set to turn off during the day and turn on at night when people are present, or it can be set to be on at any time as desired. 2. The product offers various lighting setting options, allowing customers to adjust according to their needs and adapt to different ambient lighting conditions. Anti-Interference: Our products are designed to intelligently identify useful human sensing signals and distinguish them from other environmental interference signals. This prevents false triggering of lights by signals such as mobile phone frequencies (e.g., 3 GHz), Wi-Fi signals (e.g., 2.4 GHz), TV remote signals (e.g., 433 KHz), acoustic signals, and more. Identifying interference signals ensures product reliability. Please note that the package only includes the items mentioned above; other products shown in the pictures are not included. Due to differences in lighting and monitors, the color of the item in the pictures may differ slightly from the actual product. Measurements allow for +/- 1-3 cm.
