The role of millimeter wave proximity detection device
Sep 05,2025
The core function of millimeter wave proximity detection devices (such as radar sensors) is to achieve non-contact target detection and dynamic tracking through high-frequency electromagnetic waves, which are widely used in the fields of smart homes and autonomous driving.
Smart Home Applications
Intelligent lighting: By capturing micro motion signals such as chest undulations and fingertip flipping, it can continuously determine the presence status even when the human body is still, avoiding sudden light extinction. Support hidden installation to maintain aesthetics.
Smart door lock: automatically wakes up the device and activates the networking function when approaching, increases the door opening speed by three times, and reduces contact based operations.
Environmental appliances: dynamically track the position of the human body, automatically adjust the air supply angle and speed, and achieve a comfortable experience of "wind following human movement".
Autonomous driving applications
Safety Assistance: Real time monitoring of distance and speed difference of vehicles ahead, supporting active safety functions such as adaptive cruise control and automatic braking.
Environmental perception: all-weather working ability, able to penetrate harsh weather conditions such as rain and fog, ensuring the perception accuracy of L2-L3 level autonomous driving.
Multi object recognition: Combining camera data to distinguish complex scenes such as pedestrians and low-speed cyclists, reducing the risk of lane changing.
Technical Characteristics
Penetration: It can penetrate non-metallic materials such as plastic and wood, and supports concealed installation.
Anti interference: effectively filters out interference signals such as air conditioning airflow and window noise.
Privacy protection: Only output anonymous coordinate data to avoid privacy leakage risks.
