Nowadays, PIR switch is widely used. In addition to its application in major shopping malls and public places, it is also often used in home decoration. But do you understand PIR switch? How should you choose a PIR switch?

The Introduction of the PIR Switch

PIR switch is an automatic control product based on infrared technology. When a person enters the sensing range, a dedicated sensor detects the change of the infrared spectrum of the human body and automatically turns on the load. If the person does not leave the sensing range, it will continue to be connected; after the person leaves, the load will be turned off automatically after a delay.

The main component of PIR switch is the human body pyroelectric infrared sensor. The human body has a constant body temperature, generally between 36 and 37 degrees. The passive infrared probe detects the infrared rays emitted by the human body to work. Infrared induction sources usually use pyroelectric elements, which lose charge balance when the temperature of the infrared radiation of the human body changes, and discharge charges outward. The subsequent circuit can trigger the switch after the detection and processing.

The Advantages of the PIR Switch

✔️ Easy to install

On the basis of the installation of ordinary switches, PIR switch has an extra two-core signal line. Each switch can be said to be a separate centralized controller. There is no need to add any other equipment during installation, which is easier for customers to accept.

✔️ Stability

The PIR switch has a relatively complete technical development in the product, so the transmission speed, stability, and anti-interference ability are very good. The product has a rationalized circuit safety design in the design concept to avoid short circuit and burnout of the switch.

✔️ Safe

The safety of PIR switch is better. Its switch panel is a weak current operating system, so the safety factor is high.

How to Buy a Good PIR Switch

When you buy a PIR switch, you can refer to the following two tips:

? Check the appearance of the switch panel

The switch and socket panels of PIR switch should be made of plastic products, and the surface should be smooth and textured. The material of the panel mainly has two kinds of PC and AB. Of course, some low-quality PIR switches use ordinary plastics, and engineering plastics high-end PIR switches basically use PC materials.

? Pay attention to the material

High-quality PIR switches are mostly made of bullet-proof rubber and other materials, with high fire-proof, moisture-proof, and anti-collision functions. The panel of a good switch socket is free of bubbles, scratches, and stains. The socket jack needs to be equipped with a protective shell.

A warm and safe home needs to show its quality from the details. A small PIR switch can also reveal the owner's elegant taste from all aspects. We are the wholesale PIR switch supplier. Any interests, welcome to contact us.
