Change the mounting method and detection distance of the motion sensor to improve applicability

With the continuous development of intelligent technology, motion sensors, as an important part of intelligent equipment, play an increasingly important role in security monitoring, automatic control and other fields. However, different types of motion sensors have different installation methods and detection distances, which puts forward higher requirements for users when choosing and using.

According to market research, the current common motion sensors mainly include infrared sensors, ultrasonic sensors and microwave sensors. There are significant differences in how these sensors are installed and how far they can be detected.

First, infrared sensors detect objects by detecting the reflection of infrared light. Its installation method is generally wall installation or ceiling installation, and the detection distance is usually a few meters to more than ten meters. This sensor is suitable for indoor and outdoor security monitoring as well as human sensing in smart home systems.

Secondly, ultrasonic sensors use ultrasonic echoes to detect the presence of objects. Its installation is usually fixed on the wall or ceiling, and the detection distance is generally between a few meters and twenty meters. Ultrasonic sensors are often used for vehicle and cargo detection in parking lots, warehouses and other places.

Finally, microwave sensors use the echoes of microwaves to detect objects. Its installation method is flexible and diverse, can be fixed installation or handheld installation, the detection distance is usually tens of meters to hundreds of meters. Microwave sensors are widely used in road traffic monitoring, security monitoring and other fields.

In general, different types of motion sensors have their own characteristics in terms of installation and detection distance, and users should be reasonably matched according to actual needs and the use environment when choosing them to give full play to their best functions and effects.
