1. Introduction

This user manual provides essential information for the safe and effective operation of your DEMASLED Motion Sensor Light Switch. Please read this manual thoroughly before installation and use, and retain it for future reference.

The DEMASLED Motion Sensor Light Switch provides hands-free control for your LED lights. Activated by an infrared (IR) handwave, it allows lights to turn on or off without the need to physically touch the switch. This is especially useful in areas where hands are occupied or where traditional switches are hard to reach. The switch is compatible with 12V and 24V systems, supporting up to 6A, making it versatile for various lighting setups such as closet lights, under-cabinet lighting, and LED installations in kitchens or bathrooms. The included 12V male and female connectors ensure easy and quick installation with minimal wiring. Perfect for improving convenience and functionality in everyday spaces, this sensor switch offers a reliable solution for motion-activated lighting. Ideal for closets, hallways, kitchens, and other rooms where traditional switches may be inconvenient or difficult to operate, the IR sensor ensures that your lights activate automatically when motion is detected. Its energy-efficient design also helps reduce power consumption by ensuring lights are only on when needed, contributing to a more sustainable lighting solution. Whether you are looking to upgrade your home or office with modern, hands-free lighting or simply want to add a more intuitive lighting control system, this motion sensor switch provides a practical and reliable solution for any space.

4. Setup

Follow these steps for proper installation of your motion sensor light switch:

  1. Prepare your setup: Ensure you have a compatible 12V or 24V DC power supply and LED lights.
  2. Disconnect Power: Before making any connections, ensure the power supply is completely disconnected from the mains.
  3. Identify Connectors: The sensor switch has two barrel connectors. The input connector is the male barrel connector (with a center pin) which connects to your power supply. The output connector is the female barrel connector (with an open hole) which connects to your LED lights.
  4. Connect Power Supply: Connect the male barrel connector of the sensor switch to the female output connector of your 12V/24V DC power supply.
  5. Connect LED Lights: Connect the female barrel connector of the sensor switch to the male input connector of your LED lights.
  6. Secure Placement: Place the sensor unit in a location where the handwave motion can be easily detected, such as under a cabinet or shelf. Its small size allows for discreet placement.
  7. Restore Power: Once all connections are secure, restore power to your system.

Important Note: Incorrect connection (e.g., reversing input/output) may result in the lights remaining constantly on or potential damage to the switch. Always ensure the male connector is connected to the power source and the female connector to the lights.

5. Operating Instructions

The DEMASLED Motion Sensor Light Switch operates based on infrared handwave detection:

  1. Turning On: Once power is supplied, wave your hand once in front of the sensor. The LED lights connected to the switch will turn on automatically.
  2. Turning Off: To turn off the lights, wave your hand in front of the sensor again. The lights will turn off immediately.

The sensor is designed for quick and responsive detection of a single handwave motion.

6. Maintenance

The DEMASLED Motion Sensor Light Switch requires minimal maintenance:

  • Cleaning: Gently wipe the sensor surface with a soft, dry cloth to remove dust or debris. Do not use abrasive cleaners or solvents.
  • Inspection: Periodically check the connections to ensure they are secure and free from damage.
  • Environment: Ensure the installation area remains dry and within the specified operating temperature range.

7. Troubleshooting

ProblemPossible CauseSolution
Lights do not turn on/off with handwave.
