What is a Radar Sensor Switch?

A radar sensor switch, also known as a microwave sensor switch, is based on the Doppler effect and utilizes advanced planar antennas. It can effectively suppress high-efficiency harmonics and other noise interferences, offering high sensitivity and strong reliability. This makes it a safe and convenient choice for building automation and modern property management. With low power consumption and comprehensive functionality, it can control various types of lighting fixtures. The sensor emits radar scanning signals that can penetrate wooden doors, glass, and thin walls.

Radar Sensor Switch Precautions

Applicable Scenarios: Corridors, staircases, passageways, underground garages, etc.

• Sensing Range: The radar switch's sensing range is not a perfect sphere. The front sensing distance is the longest, while the sides and back are relatively weaker. The distance marked on the product is the maximum front distance measured in the laboratory, not the distance at every angle. Different installation environments can also affect the switch's sensing range.
• Penetration Ability: The microwave radar sensor switch can penetrate most non-metallic materials, such as gypsum board, wood, glass, and plastic. It can also sense through walls thinner than 10 cm or hollow walls.
• Sensing Objects: The microwave radar switch senses moving objects, not just humans. When installed outdoors, even slight movements caused by wind or other factors might trigger the sensor. Therefore, consider whether the environment is suitable for outdoor installation, and ensure proper waterproof measures if installing outdoors.
• Installation Guidelines: To avoid signal interference between fixtures, ensure an installation distance of more than 4 meters. Make sure there are no metal obstructions in the emission part. Before installation and debugging, check whether there are any long-term moving objects within the detection range (such as fans, air conditioner outlets, or irregularly moving objects like ribbons). These could cause the lights to malfunction. Since microwave sensors have strong penetration capabilities, ensure that the wall is solid. Thin wooden or gypsum board partitions may allow external moving objects to trigger the lights mistakenly.
