LED display human radar sensor module intelligent advertising screen application, in the range of perception, no pedestrian through the advertising screen does not work. When a pedestrian passes, the advertising screen starts to work. If a pedestrian stops, they continue to work. Outdoor advertising screens not only add color to the night, but also bring trouble to citizens' travel. In order to promote their products, stores often choose large, brightly colored advertising screens to attract the attention of potential customers, thus achieving the effect of advertising. However, the bright advertising screens day and night have gradually changed from eye-catching to damaging to people's eyes, causing serious light pollution and wasting precious power resources.
In order to solve the light pollution caused by the advertising screen at night and increase the attention of pedestrians, the radar sensor module is used to display the advertising screen intelligently. The human radar induction module of LED display screen is used to detect pedestrians within the induction range, analyze the electromagnetic wave signal received by the single chip computer, control the working state of the advertising screen, and realize the intelligent display of the advertising screen.
The human radar induction module of LED display detects the target with electromagnetic wave, irradiates the target with electromagnetic wave and receives its echo, so as to obtain the distance from the target to the electromagnetic wave transmitting point, the range change rate (radial velocity), direction, Angle and other information. Radar induction module is based on Doppler effect, the induction distance is flexible and adjustable, adopts mature CMOS technology, single chip integration, cost-effective, with self-calibration function, free from external interference. Meet RED, CE, FCC, ETL and other certification standards, widely used in intelligent perception, human presence sensing, motion detection and control and other fields.
As the number of advertising screens increases, their ability to attract attention diminishes. In order to improve the light pollution brought by the advertising screen and improve attention, the LED screen human radar induction module is used to display the intelligent human body induction advertising screen. Because people tend to show a stronger interest in motion and things that change, they pay more attention. Applying this theory to the advertising screen display system can lead to better advertising capability.
Using radar sensors, when the human body approaches, the advertising screen starts to work, the sensing distance should be appropriate, the advertising screen should be able to attract the attention of pedestrians, without causing a scare. The LED display human radar sensor module works by detecting the presence of the human body. In the induction range of the radar sensor, once the human signal changes, the signal output end of the sensor will output high level, otherwise it will output zero level.
The internal integrated signal processor can directly output the induction control signal, and there are a few components outside to form a complete microwave induction sensor. It can meet the requirements of ultra-low power consumption in battery powered application scenarios, and is the first choice for upgrading traditional infrared heat release sensors. Using this property, radar sensors can sense people entering and moving within the area. If the person remains stationary, the sensor can continue to output a high level.
The radar module can automatically and quickly open all kinds of incandescent lamps, fluorescent lamps, buzzers, automatic doors, electric fans, dryers and other equipment, especially suitable for enterprises, hotels, shopping centers, warehouses, family corridors and other sensitive areas or security areas of automatic lighting, lighting and alarm systems.
LED display human radar sensor module has the advantages of high sensitivity, high reliability and low power consumption. The work of the display screen is adjusted according to the behavior of pedestrians in the detection area. The display starts when pedestrians enter the detection area and stops when pedestrians walk out of the detection area. If the pedestrian is attracted to stay in the detection area, it will continue to display until the pedestrian leaves. That is to say, within the range of perception, no pedestrian does not work through the advertising screen, the pedestrian begins to work through the advertising screen, and if the pedestrian stays, they will continue to work. The intelligent advertising screen display system improves the light pollution caused by the abuse of advertising screens and improves the advertising ability.
