Unlike traditional Infrared (PIR) sensors that require a direct line of sight, microwave radar can penetrate non-metallic surfaces such as glass, drywall, and thin wood. This allows you to completely hide the sensor inside cabinets, light boxes, or behind panels without sacrificing detection sensitivity.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 id=\"stable-performance-in-any-environment\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eStable Performance in Any Environment\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eRadar technology is immune to environmental changes that typically trigger false alarms in PIR sensors. It remains highly accurate regardless of ambient temperature fluctuations, dust, or heat sources, ensuring your lights only turn on when actual movement occurs. Once activated, the switch maintains power for a 20-second delay, automatically extending the time if continuous motion is detected.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 id=\"technician-tip\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTechnician Tip\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAlways pay strict attention to the wiring polarity and installation environment. The input (IN) uses Red (+) and Black (-), while the output (OUT) uses Red (+) and White (-). Furthermore, as printed on the factory label, \u003c\/span\u003e\u003cstrong class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003edo not install this sensor directly behind or facing a metal block\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ng-star-inserted\"\u003e. Metal surfaces will reflect the microwave signals, causing the sensor to malfunction or completely blocking its detection range.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003e(Note: While the physical board features an LDR photoresistor component, some factory batches bypass this circuit for 24\/7 operation. Please test your specific unit if daylight sensing is required.)\u003c\/span\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":68272710189207,"sku":"21PS000940","price":38.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/12v-microwave-radar-motion-sensor-switch-am-rs-05dc.jpg?v=1793954211","url":"https:\/\/scccltd.com\/products\/12v-microwave-radar-motion-sensor-switch-35w","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
