Advantages and disadvantages of microwave sensor radar LED tube light
Microwave radar sensor LED tube lights use the principle of microwave reflection, which is a kind of particle reflection, similar to ultrasonic reflection. When it is emitted, it will be reflected back when hitting an object, just like a rubber ball, through reflection-recovery to detect the movement of the object status. Only moving objects can be monitored. In actual use, attention should be paid to the selection. So what are the unique characteristics of the radar LED tube?
Radar sensor LED fluorescent lamp advantages: long sensing distance, wide angle, no dead zone, can penetrate glass and thin floors, not affected by environmental temperature and dust, the sensing distance will not be shortened, the reaction speed is fast, and the concealment is good.
Sensing principle; Microwave radar sensor LED tube lights is adopted, Doppler radar sensor principle, due to high sensitivity, the detection distance is far: Microwave radar sensor LED tube lights, the sensing distance can reach 8-10 meters, if used in the garage, the car will reach the light The light will be on at 1-3 meters. The sensing distance of the human body is 3-5 meters in winter, and the light will only turn on when the car reaches the light. In summer, the sensing distance is only 1-3 meters, and sometimes it does not turn on when the car reaches the light. The garage is generally used Slightly bright-the full bright state is better. For other aisles, warehouses, etc., it is better to use all off-all on.
Disadvantages of radar LED tube light:
The characteristics of radar sensing technology have a certain penetration ability due to the extremely short wavelength and high frequency. It can penetrate non-metallic objects, so the radar sensor can be built into the lamp. It looks like a regular LED lamp. In fact, it has radar sensor function, so the sensitivity is very strong. Of course, for metals, microwaves will be shielded and will not work. Therefore, the microwave radar sensor LED tube lights is afraid of metal, and metal will interfere with its shortcomings.
1, the installation should not be too dense, it is easy to interfere with each other, even a few centimeters thick wall can penetrate through, such as glass, wood board and other board walls.
2, the test is more difficult, and special equipment is required. During the test, any interference from dynamic things must be excluded.
3, because it is too sensitive, the anti-interference ability is reduced, and it is easy to cause false triggering. Such as small pet interference, dynamic object interference. However, infrared rays only work on the heat source, and customers are not sure how to test the quality during use. A little experience, although radar waves have strong penetrating power, they also have strong reflections when meeting metal. Using this feature, as long as the sensor head is covered with a metal cover, external interference can be eliminated.
Recommendation: Use Microwave radar sensor LED tube lights in the hot south, and radar LED tubes for long-distance detection. The effect is excellent.
