Microwave sensors are active sensors that emit high-frequency electromagnetic waves (58 GHz) and receive their echoes. The sensor can detect changes in the , and even small movements within its detection range.The microprocessor triggers the "light up" . Signals passing through doors, glass panels, and thin walls may be detected. Note: Detection of people or objects moving towards the lamp is more sensitive The high-frequency output of the sensor is less than 10mW, which only accounts for one percent of the mobile of mobile phones and microwave ovens.The product is a moving object sensor with a detection range of 360 degrees and an operating frequency of 58 GHz.The advantage of this product is stable working conditions (stable working temperature: 0 Celsius- + 70 Celsius)This product uses a microwave sensor (high-frequency output less than 02lMw), so it is safer and performs an infrared sensor.It can be installed in products made of glass or plastic, as these materials have little effect on the sensor.Specification:Working voltage: AC220 240V 50 / 60HzCharging : 400W (inductive load) / 800W (resistive load)Installation : Indoor, wall or ceiling installationHF system: 58 GHz +/- 75 MHz CW radio Band ISMDetection angle: 360 degreeDetection distance: 1-8m (Radius), adjustableOperation delay: 8 seconds to 12 minutes, adjustableLight control illumination: 2 ~ 2000LUX consumption: almost 09 WOperating temperature: -10 Celsius ~ 70 CelsiusColour: whiteMaterial: ABS+ metalSize: 87*43*39mmPackage Contents:1 * Sensor Switch1 * Screw Accessories Package1 * Instruction ManualNotes:Note: Detecting people or objects moving toward the lamp is more sensitive.The high-frequency output of this sensor is less than 10mW, which is only one percent of the mobile of mobile phones and microwave ovens.Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
