Microwave radar induction switch module Doppler radar networked garage intelligent light application, designed for underground parking lot, using intelligent two-stage brightness control, Doppler radar induction trigger, intelligent independent network communication interconnection technology, microwave radar induction switch module single light can independently adjust the movement of objects according to the induction range (microwave induction area is 3~20 meters). No one or vehicle movement in the lamp induction area, the power is only 3W, the brightness is equivalent to more than 13W energy-saving lamps, enough to meet the electronic monitoring and personnel inspection; When people or vehicles move in the induction area, the microwave induction trigger lights up (power is 10W), and the illumination is equivalent to 40WT8 solar lamp. The brightness of the microwave radar induction switch module is delayed until 30 seconds after no one or vehicles move within the induction range. When the single light is on, it sends an automatic network signal to the network induction area, and lights up at the same time after receiving the automatic network signal to achieve the effect of regional network lighting.
The microwave radar induction switch module area light always keeps the light above 15 meters in front of the vehicle on in advance. Solve the problem of lag of all microwave lamp tubes in the market, improve the garage lighting effect on demand, so that owners are more satisfied.
Microwave radar induction switch module product features:
1. Super energy saving: under the same lighting conditions, energy saving 80-90% than traditional fluorescent lamp;
2. Comfortable lighting experience: Compared with the slow sensing and sparse lighting caused by the difference in sensitivity of a single lamp, the lamp flickers frequently and the driving vision is dark. Microwave radar induction switch module intelligent AD hoc network connected microwave induction lights can ensure better lighting effect in the forward looking area 15-20 meters in front of the vehicle after entering the induction area.
3. Simple installation: no ballast, starter, intelligent control switch, low power requirements on the power supply line. Compared with the common centralized control or regional intelligent control through the single light address positioning code in the market, the AD hoc network can install the single light without difference, and the microwave radar induction switch module can greatly reduce the engineering cost.
4. Super long life: 5 to 100 thousand hours of service life, 20 times that of energy-saving fluorescent lamp, 100 times that of incandescent lamp, than ordinary
Microwave radar induction switch module LED light more reliable:
1. Vehicles entering the parking lot:
After entering the range of microwave radar induction switch module, the luminaire sends out the network bright signal to the luminaire within the network range at the same time, and the whole area is bright.
2. With the movement of people and vehicles, the double brightness lights in the 15m area before and after the microwave radar induction switch module are always bright.
None of this is a problem:
1. The application of radar induction lights in parking lots will not cause inconsistent lighting and poor sensory perception.
2, microwave radar induction switch module is not interfered, fast response.
3, microwave radar induction switch module induction distance, 1-20 meters in front of the car bright, driving feeling good.
4, solve the system control intelligent dimming zigbee or dal1 poor driving experience, high implementation cost, construction difficulties.
Microwave radar sensor switch module how to detect the living, PIR human body infrared sensing and ultrasonic ranging module sense human activities. One of them worked by sensing changes in infrared light and the other by sensing changes in ultrasound. Their perceptual accuracy is easily affected by environmental conditions, such as not being able to detect through obstacles. Are there sensors that are more cost-effective than these?
The answer, of course, is yes. Today, Xiaobian will introduce a magic microwave radar induction switch module that detects the presence of the human body through electromagnetic waves. When most people hear the word radar, they think of such a large radar or millimeter-wave radar, which is now popular in the smart home sector and operates in the 5.8GHz to 24GHz band.
The microwave radar induction switch module introduced today is small in size, the price is only a few yuan, and the operating frequency is about 5.8G. It works the same way as most radar, relying on the Doppler effect.
Doppler effect of microwave radar induction switch module:
You can talk about the phenomenon of life in middle school physics: the noise of an oncoming ambulance gets louder and louder; As the car moves away, the sound gets lower and lower. This is known as the "Doppler effect." It is named in honor of Christian Johann Doppler, an Austrian physicist and mathematician. In 1842, he first proposed the theory that the wavelength of an object's radiation varies depending on the relative motion of the source and the observer. In front of the moving wave source, the wave is compressed, the wavelength is shorter, and the frequency is higher (blue shift); Behind a moving wave source, the opposite effect occurs. Longer wavelength and lower frequency (RedShift RedShift); The higher the velocity of the wave source, the greater the effect. From the degree of movement of the wave red (blue), the velocity of the wave source moving in the observed direction can be calculated.
