1. Wide Range Of Sensing, Low Impact Of High Temperature, Hidden Installation, Penetrating Sensing2. Sensing The Change Of Object Displacement Is Different From The Human Body Sensor Switch, Which Mainly Senses The Change Of Infrared Rays. When The Ambient Temperature Is High, It Is Difficult To Distinguish And The Distance Becomes Closer. The Microwave Radar Sensor Switch Is Not Affected!3. Penetrating Sensing, Can Penetrate Plasterboard/Glass/Plastic/Acrylic/Wooden/Thin Wall, Etc., And Can Be Installed Hidden In The Lampshade. Cannot Penetrate Metal Plates!4. Long Distance, Wide Range, 416 Meters MultiLevel Sensing Distance Adjustable, Higher Sensitivity Than Infrared Sensing5.
