Human sensing radar human sensing switch wiring diagram from principle to practice analysis

With the continuous development of science and technology, human sensing radar human sensing switch is more and more widely used in home and commercial facilities. This advanced sensing technology, with its efficient, convenient and energy-saving characteristics, has gradually become an important part of smart home and commercial space. This paper will analyze the working principle, wiring method and application scenario of human sensor switch of human sensor radar in detail, to help readers better understand and master the practical application of this technology.

First, the working principle of human sensor radar human sensor switch

Human sensing radar Human sensing switch is a non-contact detection device using microwave radar technology. By transmitting microwave and receiving the reflected signal, it calculates the round-trip time difference of microwave, so as to determine the distance and moving speed of the measured object. When the human body enters the sensing range, the microwave signal is reflected back, and the sensor receives the reflected signal and triggers the switch action.

Two, wiring methods

The wiring of human sensor switch of human sensor radar is generally divided into three parts: power line, control output line and ground line. The specific steps are as follows:

Power line access: The human sensor radar human sensor switch needs to be connected to the power supply, usually 220V AC. When connecting the power supply, ensure that the power switch is turned off to prevent short circuit accidents.

Control output line access: The human sensing radar human sensing switch usually has two sets of output lines, a group of normally closed output (NC), a group of normally open output (NO). Select a group of access control devices as required. When connecting, please note that the red line is connected to the positive terminal and the black line is connected to the negative terminal.

Ground wire access: In order to improve safety, the human sensor switch of the human sensor radar needs an access ground wire. When grounding cables, ensure that the ground cables are in good contact with the ground and that the distance between the ground cables and power cables is certain.

3. Application scenarios

Human sensing radar Human sensing switches have a wide range of applications in home and commercial facilities. For example, in the family environment, it can be installed in the corridor, bedroom, bathroom, etc., to achieve the intelligent lighting effect of people to light up, people walk off the light; In the commercial space, more efficient energy management can be achieved through interaction with other smart devices.

4. Precautions

During the installation process, please pay attention to avoid the sensor is on the air conditioning, large metal objects and other interference sources, so as not to affect the induction effect.

After installation, perform a functional test to ensure that the switch correctly detects the human body and triggers the switch action.

In the process of use, if you encounter problems or faults, do not disassemble or repair the sensor at will to avoid electric shock or damage to the device. You are advised to contact professional maintenance personnel.

During the installation and maintenance process, please pay attention to the relevant safety regulations to avoid the occurrence of electric shock, short circuit and other safety accidents.

V. Summary

As an advanced intelligent home device, human sensing switch has a wide range of application prospects and potential. By mastering its working principle, wiring methods and application scenarios, we can better use this technology to bring more convenience and energy saving effects to our living and working environment. It is hoped that this paper can help readers to have a more comprehensive understanding of the human sensor switch of human sensor radar.
