It detects waves from the human body or objects carrying wave frequencies that are sensitive to this frequency. When movement occurs within the sensing area, it triggers a signal to the switch (relay) to turn on the light. It is not affected by ambient temperatures above 32\u00b0C and can detect through wooden partitions, glass, thin walls, plasterboard, and more.<\/li>\n<li>Automatically turns on the light when someone moves within the detection area. The SENS distance adjustment function allows the sensing range to be adjusted as needed, making it suitable for different spaces.<\/li>\n<li>Combined with the adjustable LUX function for ambient brightness. If the surrounding light is bright enough, the light will not turn on, helping save electricity.<\/li>\n<li>Switch <a href=\"https:\/\/kawasan.vn\/en\/product-category\/cong-tac-cam-ung\/cong-tac-cam-ung-vi-song\/\" target=\"_blank\" rel=\"noopener\">Microwave Sensor<\/a> RS02D2 features continuous motion detection.
