  • How does the human body sensor switch connect the small night light radar sensor more intelligent

    2023-11-30 475

    I. Introduction


    With the continuous development of science and technology, intelligent home has become the choice of more and more people. Among them, the human body sensor switch night light is a very practical intelligent equipment, which can automatically turn on and off the light according to the movement of the human body, bringing more convenience and comfort to our night. This article will introduce the wiring method of the human body sensor switch night light in detail, and how to use it with radar sensors to make your night more intelligent.

    Second, the wiring method of human body induction switch night light


    Confirm power supply


    First, you need to confirm whether your nightlight is powered by AC or direct current. If it is AC, it is necessary to use an AC transformer to reduce the voltage to the range suitable for the night light; If it is direct current, you can use the power adapter directly.


    Prepare materials


    You need to prepare the following materials: human sensor switch night light, power cord, wiring tool, edge tape and double-sided tape.


    Wiring procedure


    (1) Insert the power cord into the power socket of the night light, and ensure that the positive and negative poles of the power cord are consistent with the identification of the night light.


    (2) Use wiring tools to connect the line of the human body sensor switch with the line of the night light. Under normal circumstances, the human body induction switch will have three lines, respectively, power line, signal line and ground line. You need to connect the power cable to the power input of the night light, the signal cable to the induction input of the night light, and the ground wire to the ground end of the night light.


    (3) After connecting the line, use edge tape and double-sided tape to fix the line in the appropriate position to prevent the line from loosening or falling off.


    (4) Install the night light in the appropriate position and ensure that it is firmly installed.


    3. Use with radar sensors


    Although the human body sensor switch night light can automatically turn the light on and off according to the movement of the human body, in some specific cases, such as when the human body is stationary or does not move for a long time in the dark, the night light may misjudge the human body has left, thus prematurely closing the lamp. To solve this problem, we can consider the use of small night lights in conjunction with radar sensors.


    Radar sensor is a kind of equipment that uses microwave to detect target. It can detect the presence and movement of target by transmitting microwave and receiving echo. By placing the radar sensor in the right place, such as in the corner of a room or on the ceiling, the entire room can be covered. When someone enters the room, radar sensors can detect the presence of the person and trigger the nightlight to turn on. At the same time, when the person leaves the room, the radar sensor will also detect the person's departure and trigger the shutdown of the night light. This avoids the problem of the night light turning off prematurely.


    4. Precautions


    When wiring, be sure to turn off the power first to avoid electric shock.

    When installing night lights and radar sensors, be sure to fix them firmly to avoid falling or damaging the equipment.

    When using radar sensors, be sure to avoid the interference of metal objects or large metal objects, so as not to affect the induction effect.

    In the process of use, if you find abnormal conditions, be sure to stop use in time and check maintenance.


    V. Summary


    The human body sensor switch night light is a very practical intelligent equipment, which can automatically turn on and off the light according to the movement of the human body, bringing more convenience and comfort to our night. Through the use of radar sensors, we can further improve the use of night lights, so that our night is more intelligent. When installing and using, we must pay attention to the safety and maintenance of the equipment.
