Radar human body sensor switch manufacturers human body sensor switch sensing range

With the continuous development of science and technology, radar human sensor switch, as a smart home control device, has been paid more and more attention. This kind of switch controls the circuit by sensing the electromagnetic wave emitted by the human body, which brings great convenience to people's life. So, how wide is the range of radar human sensor switch manufacturers human sensor switch? This article will be introduced in detail from the following aspects.

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

The working principle of the human body sensor switch is to use the microwave radar's ability to sense the human body, and detect the electromagnetic wave changes generated by the human body movement through the built-in sensor, so as to control the switch on and off. When the human body enters the detection range of the radar wave, the sensor will receive the reflected electromagnetic wave, which triggers the switch on and off.

Second, the sensor range of the radar human sensor switch

The sensing range of the radar sensor switch is mainly affected by two factors: the transmitting power and receiving sensitivity of the radar wave. Generally speaking, the sensing distance of the radar human sensor switch is between 1-30 meters, and the specific value will be affected by product design and environmental factors.

3. Factors affecting the sensing range of the radar human sensor switch

Transmitting power

The greater the transmitting power of the human sensor switch, the greater its detection range. Therefore, in order to improve the induction range of the product, some manufacturers will increase the transmission power. However, too much transmission power will also have an impact on human health, so it is necessary to make appropriate adjustments under the premise of ensuring safety.

Receiving sensitivity

The receiving sensitivity of the radar body sensing switch will also affect its sensing range. The higher the sensitivity, the weaker the electromagnetic wave changes can be detected, thus expanding the induction range. However, too high sensitivity is also susceptible to interference from environmental noise, affecting stability.

Environmental factor

Environmental factors will also affect the sensing range of the radar human sensor switch. For example, when reflected on the surface of metal objects, glass, walls and other media, it will affect the propagation of electromagnetic waves, thereby narrowing the induction range. In addition, the complexity of the indoor environment will also affect the sensing range, such as the placement and occlusion of furniture, curtains and other items in the room.

Four, how to correctly use the radar human sensor switch

In order to give full play to the role of radar human body sensor switch manufacturers human body sensor switch, the correct use is as follows:

The radar body sensing switch is installed in the center of the area to be controlled in order to cover the detection range to a large extent.

When installing, pay attention to avoid installation on metal objects, glass, walls and other medium surface reflection, so as not to affect the propagation of electromagnetic waves.

After the installation is completed, the sensing range of the radar human body sensing switch is adjusted to adapt to the complexity of the home environment.

Five, radar human body sensor switch manufacturers human body sensor switch application scenario

As a smart home control device, radar body sensing switch is suitable for many scenarios. Here are some common scenarios:

Home lighting system

In the home lighting system, the radar body sensing switch can be used to control the lighting in the room. When someone enters the room, the lights automatically turn on and off when they leave, eliminating the trouble of manually turning on the lights.

Smart home control system

In the smart home control system, the radar body sensing switch can be used in conjunction with other smart devices. For example, when the human body enters the room, the induction switch can automatically turn on the air conditioning, TV and other equipment to create a comfortable living environment.

Office space

In the office space, the radar human sensor switch can be used to control lighting, air conditioning and other equipment. When employees enter the office, the lights will automatically turn on and the air conditioning will automatically turn on to improve work efficiency.

Industrial application

Radar human sensor switch manufacturers Human sensor switches are also widely used in industrial applications. For example, in a factory production line, when a worker enters the work area, the production line automatically starts, and when it leaves, it automatically stops, improving production efficiency.

Six, the advantages and disadvantages of radar human sensor switch

As a smart home control device, radar human sensor switch has the following advantages and disadvantages:

Advantages:

Wide sensing distance: Generally speaking, the sensing distance of the radar human body sensing switch is between 5-8 meters, which is suitable for control in a large space range.

High sensitivity: The sensitivity of the radar human body sensor switch is high, and it can quickly sense the movement of the human body.

Energy saving and environmental protection: By sensing the movement of the human body to control the switch on and off, you can effectively save energy, but also reduce the impact on the environment.

Easy installation: The installation of the radar human sensor switch is relatively simple, just fix the switch on the wall.

Low maintenance cost: Due to the simple structure of the radar human sensor switch, the maintenance cost is low.

Cons:

False trigger: Because the radar human sensor switch is controlled by sensing changes in electromagnetic waves to switch on and off, it may be triggered by electromagnetic wave interference in the environment.

Higher price: Compared with ordinary switches, the price of radar human sensor switches is higher, which may increase the overall cost.

Limited scope of application: The radar human sensor switch is not suitable for the control of metal surfaces, and may have limitations for some special environments and uses.

Vii. Conclusion
