Integrating LED sensor switches into smart homes is one of the hot topics in the current home intelligence. With the development of science and technology, smart homes are becoming more and more popular. The experience of "lights automatically turn on", "turn on when you approach", "turn on when you wave your hand", "turn on when you open the cabinet", and "lights turn off when you leave" is no longer a dream. With LED sensor switches, you can easily achieve lighting automation without complicated wiring or high budgets. It is worth mentioning that you can do all this by yourself!
1. What is an LED sensor switch?
The LED sensor switch is a sensor that uses light beams to detect and identify objects. It is an intelligent module that combines LED lamps with control switches. Light sensor switch usually work at a low voltage of 12V/24V and are small in size. They are suitable for integration in cabinets, drawers, wardrobes, mirror cabinets, desks, etc.
It can automatically control lighting in the following ways:
(1) Hand shaking sensor(Non-contact control): Within 8CM of the switch installation location, you can control the light by waving your hand.
(2) PIR sensor switch (Automatically turns on when approaching): Within a range of 3 meters (no obstacles), the PIR sensor switch senses any human movement and automatically turns on the light. When leaving the sensing range, the light automatically turns off.
(3) Door trigger sensor switch (Automatically turn on and off the light as the cabinet door opens and closes): Open the cabinet door, the light turns on, close the cabinet door, the light turns off. Some switches can also switch between hand scanning and door control functions.
(4) Touch dimmer switch (touch switch/dim): Just touch the switch with your finger to turn on, turn off, dim, etc.

|
Material/Equipment |
Recommended description |
| LED sensor switches | Such as hand scanning induction, infrared induction, touch dimming and other styles |
| LED cabinet lights, welding-free light strips | Recommended Weihui light strips, with many styles and affordable prices |
| 12V/24V LED power supply (adapter) | Select a power supply that matches the power of the light strip |
| DC quick-connect terminal | Convenient for quick connection and maintenance |
| 3M glue or aluminum profile (optional) | For installing the light strip, more beautiful and heat dissipation |
| Smart controller (optional) | For integration into smart home platforms, such as Tuya smart APP, etc. |
3. Installation steps
✅ Step 1: First connect the LED light strip to the LED sensor switch, that is, connect the LED light strip to the output end of the sensor switch through the DC interface, and then connect the input port of the switch to the LED driver power supply.
✅ Step 2: Install the lamp, fix the lamp at the target position (such as under the cabinet), and align the sensor with the sensing area (such as hand scanning, touch area or wardrobe door opening).
✅ Step 3: After turning on the power, test the installation results, test whether the connection route is normal, and whether the switch is sensitive.
4. How to connect to the smart home system?
To achieve remote control (brightness, color temperature, color), voice/music control or automatic scene linkage, you can use Weihui's Wi-Fi five-in-one LED remote light sensor. This smart receiver can be used with a remote control sender or with the Smart Tuya APP. Both are available.
This Wi-Fi five-in-one LED remote light sensor can switch between single color, dual color temperature, RGB, RGBW, and RGBWW color modes. Select the color mode according to the function of your LED light strips (each remote control sender corresponds to a different light strip, such as the CCT of the light strip is RGB, then the corresponding RGB remote control sender should also be selected).
Whether you are a smart home novice or a home improvement DIY enthusiast, light up the future, starting now. DIY LED sensor switches are not only economical and practical, but also can greatly improve the quality of life. If you need it, please tell me directly your specific purpose or scene (such as kitchen, entrance, bedroom DIY), Weihui can provide you with one-stop customization.
