Description
Item details
The YW02B infrared motion detector is a compact ceiling-mounted sensor designed to automate lighting systems in indoor environments. By sensing changes in infrared radiation caused by human movement, the device can automatically control connected lighting equipment.
Once a person enters the sensing zone, the sensor immediately triggers the light. When no movement is detected for the preset delay period, the lighting system switches off automatically, helping reduce unnecessary power consumption.
The 360° sensing coverage ensures the device can monitor movement from all directions. The sensor also includes an adjustable ambient light control, allowing users to determine whether the device should operate in daylight or only under low-light conditions.
With flexible delay settings and reliable detection performance, the YW02B sensor provides an effective solution for energy-efficient lighting automation.

FAQ
What is the purpose of a PIR motion sensor?
A PIR sensor detects infrared radiation emitted by the human body and automatically controls electrical devices such as lighting systems.
What detection area does the YW02B cover?
The sensor provides 360-degree coverage with a maximum detection distance of approximately 6 meters.
Can the sensor be adjusted to work only at night?
Yes. The built-in daylight sensor allows users to set the sensor so it operates only when ambient light levels fall below a selected value.
How long can the light stay on after motion is detected?
The delay time can be adjusted between 5 seconds and 6 minutes.
Where should this sensor be installed?
The sensor is designed for ceiling installation and works best in indoor spaces such as corridors, offices, garages, and residential buildings.
