Pet Activity Monitor Kit with Arduino Nano – Smart Night Light for Your Pet

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

Your pet doesn't need to wander in the dark. With this kit, kids build a night light that automatically brightens when their cat, dog, or rabbit approaches and dims when the area is empty. It's a real-world lesson in sensor fusion – using a PIR motion detector and an LDR to create a power-saving, pet-friendly light.

What You'll Build

You'll assemble a complete pet activity monitor on a breadboard. The LDR measures ambient light; when it's dark, the PIR sensor watches for motion from a passing pet. On detection, the high-brightness white LED smoothly turns on at full brightness, then fades down a few seconds after the pet leaves, saving energy and keeping your pet comfortable.

What You'll Learn

• Wire an LDR and PIR sensor to Arduino analog and digital pins
• Use a MOSFET to control a high-power 3W LED without overloading the Arduino
• Program conditional logic that reads two sensors and adjusts LED brightness in real time
• Understand how everyday automation systems save power by responding to presence and light levels
