Applications

Tips: The working principle of the millimeter-wave human presence sensor

The millimeter-wave radar human presence sensor detects human movement and rest by transmitting and receiving millimeter-wave signals and utilizing the Doppler effect and phase changes. The sensor can penetrate thin obstacles (such as glass and wooden boards) to detect targets. Even when the human body remains stationary, it can perceive through subtle signal changes generated by slight movements such as breathing. The internal signal processing algorithm will filter and identify the collected raw data, thereby achieving high-precision measurement of human presence and distance, which is suitable for scenarios such as smart home, lighting control, and security monitoring.
