What happens in this clip
Connect the Lux sensor and PIR motion sensors. The Lux sensor is plugged into one of the 'Lux Input' ports (C or D) at the front of the controller. Next, connect the two PIR motion sensors. One PIR sensor is plugged into 'PIR Input A', and the other PIR sensor is plugged into 'PIR Input B'. These connections are simple plug-and-play. Finally, connect the Pixel LED strip's power connector to its adapter, completing all the wiring. Once wiring is complete, refer to the user manual or the video's explanation for setting up the physical installation of the LED strips and sensors on a staircase for optimal performance, though this physical installation is not explicitly demonstrated.
Goal: Connect the Lux and PIR sensors to the controller and complete all wiring.

About the full video
This project provides a comprehensive guide on setting up and programming an automatic stair light controller. It involves unpacking the controller and its components, wiring the power supply, connecting an RGB Pixel LED strip, and attaching motion (PIR) and light intensity (Lux) sensors. The instructions detail how to program various settings such as LED quantity, color mode, speed, time delay, and brightness, culminating in a demonstration of the motion and light-sensitive stair lighting system.
Step 5 of 7: Wire Motion Sensors and Power Supply
Wire the motion sensors according to their manufacturer's instructions. Typically, the sensor will be connected between the power supply and the LED strips. Ensure correct polarity. The power supply will then be connected to a mains power source.

Questions about Staircase Lighting
What are the most crucial safety precautions I need to take when installing electrical components for this project?
Always turn off the power at the circuit breaker that controls the staircase's lighting circuit before starting any wiring. Double-check that the power is off using a voltage tester. If you're unsure about any electrical work, consult a licensed electrician to ensure compliance with local codes.
Is a soldering iron truly necessary, or can I use an easier method to connect the LED strips?
While soldering provides the most robust and reliable electrical connection for LED strips, many beginner-friendly kits offer solderless connectors. These 'quick connectors' simply clip onto the strip ends, making the process much faster and easier if you're not comfortable with soldering.
What type of LED strips and motion sensors should I choose for the best results on a staircase?
Opt for 12V LED strips with a consistent light output (e.g., 60 LEDs/meter) and a warm color temperature (2700K-3000K) for a cozy ambiance. For motion sensors, choose PIR (Passive Infrared) sensors with adjustable sensitivity and time delay, ensuring they cover the top and bottom of your staircase effectively.
What is a common mistake beginners make with motion-activated lighting, and how can I avoid it?
A frequent mistake is improper motion sensor placement or sensitivity settings. To avoid this, temporarily position and test your sensors before final mounting. Experiment with their angles and sensitivity to ensure they reliably detect movement on the stairs without false triggers or dead spots.
Is the 8-hour estimated time realistic for someone new to DIY electrical projects?
Eight hours is a reasonable estimate for a beginner, assuming you have all materials and tools ready. Planning the layout, carefully cutting and connecting strips, and concealing wiring can take significant time. Working methodically and allowing for troubleshooting will help you stay within or close to this timeframe.
What are the best methods for concealing all the wiring and making the installation look professional?
To achieve a clean look, route wires along discreet edges, such as under stair nosings or behind the kick plate. Use small adhesive cable clips or wire channels that match your staircase color. Planning your power supply and sensor locations carefully from the start will minimize visible wires.
Are there any alternative power supply options if I don't want to hardwire the system?
For permanent motion-activated staircase lighting, a dedicated wired 12V power supply (transformer) is recommended for consistent performance and safety. While some temporary LED solutions use batteries or USB, these are generally not suitable for a robust, always-ready staircase illumination system.
