and High Quality. The microwave sensor is an active sensor, and the HF sensor emits high frequency electromagnetic waves (5.8 GHz) and receives their echoes. This sensor detects changes in the or even tiny movements within its detection range. The microprocessor triggers the "lights up" . Signals passing through the door, glass plates and thin walls may be detected. This 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 condition (stable operating temperature: 0C - 70C) This product uses a microwave sensor (high frequency output is less than 0.2lMw), so it is safe and performs infrared sensor. It can be installed in products made of glass or plastic, as these materials have little effect the sensor. Working voltage: AC220V-240V 50Hz/60Hz Load power: 600W (inductive load) / 1200W (resistive load) Installation method: indoor, wall or ceiling installation HF system: 5.8GHz /-75MHz CW radio wave, ISM band Detection angle: 360 Detection distance: 1-8m (radius), adjustable Working delay: 8 seconds to 12 minutes, adjustable Light control illumination: 2-2000LUX Power consumption: nearly 0.9W Working temperature: -10C - 70C Note: The detection of 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. Colour:As Shown Material:plastic Package Contents: 1 x sensor switch(Due to different product batches, the appearance , which does not affect the use) Only the above package content, other products are not included. Note: Light reflection 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.
