Human radar has a sensor switch to help solve the problem that lamps are always misjudged

Human radar has sensor switches to help solve the problem of misjudgment of lamps and lanterns. As we all know, if the sensor switch products are installed too tightly, they will be disturbed. Therefore, in order to prevent interference, it is recommended to set an installation distance of more than 2.8 meters for radar detection lighting equipment, but many application scenarios need to shorten the installation distance to achieve good road brightness.

how to solve this problem?

Anti-jamming is the market development trend of sensor switches for human radar, and products with sensor switches have strong interference ability. According to market research, induction switches can be divided into three types: voice-activated switches, infrared switches and radar induction switches. The radar sensor switch is a moving object detector designed using the Doppler effect principle. It detects whether the position of the object is moving in a non-contact manner and switches accordingly. It is not affected by temperature, environment, dust and wireless anti-interference.

The human radar presence sensor switch can be installed on a certain thickness of plastic, glass, wood and other non-metals, and it can penetrate these materials to sense moving objects. Equipment control, ambient auxiliary lighting control, underground parking lot, corridor lighting and other fields do not affect the detection function technology.

Voice-activated switch: It needs to generate a certain sound, which will affect the rest of the surrounding residents. It is easily disturbed by external sounds, often misjudged, with short lifespan and limited load.

Infrared switch: The infrared probe needs to be kept clean for a long time, cannot be hidden, and has low sensitivity. It is affected by the environment such as temperature, airflow, and light, and the detection range is small.

Due to performance defects, voice-activated switches and infrared switches are not suitable for stable use in underground parking lots and outdoors.

The human body radar presence sensor switch overcomes the shortcomings of the above two switches, with high sensitivity, large detection range, strong anti-interference ability, wide application range, long product life, and can be directly installed on the lampshade to control lighting. Installed in the lampshade to facilitate the installation of corridor lighting. It can be used in corridors, elevators, toilets, underground parking lots, outdoors and other places. Radar sensor switches can be used where voice and infrared switches do not work properly.

1. Large open-air parking lot, supermarket underground parking lot lighting control;

2. Community underground parking lot lighting control;

3. Indoor and outdoor safety prevention systems, on-site safety warnings and other places.

4. Home bathroom lighting, kitchen ventilation and exhaust control;

5. Control the automatic door switches of banks, shopping malls and other stores;

6. Important places that need to monitor the movement of objects.

In life, the widely used sensor switches mainly include human body sensor switches. Infrared sensor switch and microwave sensor switch. Inductive switches refer to switches that integrate and control circuits through related equipment.

The switch will always be on as long as the person is not within the range of the sensing switch, and if the person leaves the sensing area, the switch will automatically turn off.

Install and debug the sensor switch:

1. Inductive switches can be divided into external inductive switches and embedded inductive switches.

2. The size of the external sensor switch is the same as that of the wall switch, and the existing wall switch can be directly replaced.

3. The installation method of the ceiling sensor switch is different from that of the general switch. It does not affect obstacles such as the induction function board, and the induction effect is good.

4. The left and right sides of the switch are larger than the sensing range of the upper and lower sides. Therefore, when installing the switch, it should be ensured that the two axes are as perpendicular to the direction of the pedestrian passage as possible to achieve the best perception effect.

5. Start after installing the switch. If the ambient light is sufficient, the lamp will flash three times. One minute after initialization, the switch enters the working state. Cover the ambient light with an object to make the switch work properly. The switch will always work if people don't leave the sensing area. After the person leaves, the switch will automatically delay the load off.

6. If you don't like the delay or light sensitivity value, you can adjust it by switching the control button on the back of the product.
