Microwave sensors are active sensors that emit high-frequency electromagnetic waves (5.8 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 power 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 5.8 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 0.2lMw), so it is 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 / 60Hz Charging power: 400W (inductive load) / 800W (resistive load) Installation : Indoor, wall or ceiling installation HF system: 5.8 GHz +/- 75 MHz CW radio Band ISM Detection angle: 360 degree Detection distance: 1-8m (Radius), adjustable Operation delay: 8 seconds to 12 minutes, adjustable Light control illumination: 2 ~ 2000LUX Power consumption: almost 0.9 W Operating temperature: -10 Celsius ~ 70 Celsius Colour: white Material: ABS+ metal Size: 87*43*39mm Package Contents: 1 * Sensor Switch 1 * Screw Accessories Package 1 * Instruction Manual Notes: 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 power 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.
