Build an Auto-Dimming Corridor Light with Arduino Uno & LDR Motion Sensor Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Create a home security system that responds intelligently to light and motion. Your corridor stays softly lit until someone approaches at night — then the LED strip brightens automatically, guiding the way while conserving energy. The kit pairs a PIR motion sensor with two LDR light sensors and a MOSFET driver to control a 12V LED strip (not included), giving you real-world experience in designing a responsive environment.

What You'll Build

You’ll assemble a functional motion-activated corridor light that dims during the day and reacts to movement after dark. The finished circuit reads ambient light continuously, suppresses false triggers via dual LDR placement, and switches a high-brightness LED strip on only when needed. It’s a practical addition to any hallway or entryway that you can install permanently after testing on the breadboard.

What You'll Learn

• Interface a PIR motion sensor and LDR with Arduino Uno for real-time sensor fusion
• Program logic that distinguishes day, night, and motion events to control an LED strip
• Use an IRF540N MOSFET with gate protection to safely drive high-current loads
• Apply voltage dividers and filter noise for reliable LDR readings

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project fits perfectly into CBSE Class 11-12 physics or computer science coursework, first-year B.Tech ECE/EEE labs, and Smart India Hackathon prototypes requiring IoT or home automation. ATL Tinkering Labs and college maker spaces will also find it a ready-to-run solution that teaches sensor integration without endless breadboarding. If you’ve tinkered with Arduino before and want to move beyond blinking LEDs, this kit gives you a real-world system to own.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
