What is a Motion Sensor?

A motion sensor is a device that can identify and detect human, animal or solid motion. They are often used in security, lighting control and automation systems to trigger a response when motion is detected. Next, we will introduce the working principle and main types of TIOSL sensors.

How Does it Work?

Our motion sensors have a two-stage mechanism: detection and response. When they detect motion within a specified area, they trigger a predetermined reaction, such as turning on a light.

Main Types of Motion Sensor

Infrared Motion Sensors

Infrared sensors detect changes in infrared radiation caused by the movement of warm bodies, such as people or animals. There are active and passive infrared motion sensors.Our infrared sensors can detect motion and trigger pre-set responses. Since our sensors are usually used in smart lighting control systems, the response to triggering the infrared sensor is to turn on the light. When someone approaches, the lamp will automatically turn on the light without manual control.

Microwave Motion Sensors

Microwave motion sensors detect motion by emitting microwave signals at a specific frequency and then observing how the signal is reflected by moving objects. The difference between the transmitted and reflected signals can be used to assess whether there is motion in the coverage area. When motion is detected, its reaction is the same as that of infrared sensors, and it can automatically turn on lights.
