Radar human sensor helps classroom UV sterilization

Radar human sensor sensing technology realizes ultraviolet sterilization and disinfection in classrooms. The classroom is the main place for teachers to impart knowledge to students and acquire knowledge. The air quality in the classroom is extremely important for teachers and students.

The radar human sensor can be combined with the automatic control lighting and ultraviolet disinfection equipment to realize a brand-new automatic classroom disinfection equipment, without the need to modify the existing lighting circuit, with simple operation and low cost. 90% of the electric energy of LED bulbs is converted into visible light (80% of the electric energy of ordinary incandescent lamps is converted into heat energy, only 20% of electric energy), the required voltage is low, the current is small, the heat is small, and there is no safety hazard.

At the same time, the use of radar human sensor sensing technology and light intensity detection technology solves the intelligent problem of automatically turning on the lights in the classroom. When it is detected that there is no one in the classroom, the disinfection equipment will be automatically turned on to purify the air. Therefore, according to different lighting and disinfection measures, ensure the safety and comfort of the staff and maximize the sterilization effect.

A radar body sensor is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves to radiate the target and receives the target echo, so as to obtain information such as the distance change rate, azimuth, and angle from the target to the electromagnetic wave emission point. It conforms to RED, CE, FCC, ETL and other certification standards, and is widely used in lighting perception, ergonomics , motion detection and control.

When sterilizing with UV equipment, be aware that UV rays are harmful to the human body, especially the eyes and skin. The human body will become red under short-term exposure, and long-term exposure will cause redness and tearing of the eyes. With the radar human body sensor, once the radar detects the human body and enters the ultraviolet range, the ultraviolet light will be automatically turned off to realize the safety protection of the personnel.

Indoor lighting and personnel condition monitoring using radar. On the premise of ensuring the safety of personnel indoors, the ultraviolet disinfection effect is maintained. The brightness of the light can be automatically switched according to indoor and outdoor personnel and lighting conditions, energy saving and environmental protection, good disinfection effect, radar is not disturbed by light sources, etc., and can be used in smart homes and smart security.

The radar human body sensor adopts single chip microcomputer and sensor technology to realize the automatic switching of classroom automatic lighting and indoor air circulation sterilization. Its advantages are: automatic control, no manual intervention, and labor saving.
