Infrared Smart Sensor Function Explanation

The infrared smart sensor function is a feature that allows a device, such as under-cabinet lights, to automatically detect motion within a certain range and activate or deactivate accordingly. Here's a more detailed explanation:

1. Motion Detection:
   The infrared sensor uses passive infrared (PIR) technology to detect body heat or motion. When someone moves within the sensor’s detection range (typically 10-13 feet), the sensor picks up the infrared radiation emitted by the body and triggers the light to turn on.

2. Automatic Activation:
   Once motion is detected, the lights automatically turn on, providing hands-free convenience. The sensor only activates when there is human movement, ensuring energy efficiency by avoiding unnecessary lighting.

3. Auto-Off:
   After a certain period of inactivity (typically 15-20 seconds), the sensor will automatically turn off the lights to conserve energy, ensuring the light is only on when needed.

4. Sensitivity Settings:
   Many infrared sensors allow you to adjust the sensitivity of detection, which helps avoid false triggers (e.g., pets or passing traffic) and can be set to detect movement from a larger or smaller area depending on your needs.

5. Day/Night Modes:
   Some advanced infrared sensors come with day and night detection modes. During daylight, the sensor may stay inactive to save power, while at night, it becomes more sensitive to detect movement even in low-light environments.

This infrared sensor function provides convenience, energy efficiency, and seamless lighting, especially in spaces where traditional switches might be hard to reach or where hands-free operation is preferred.
