Pet Activity Monitor Kit with Arduino Uno + Relay
Pet Activity Monitor Kit: Motion-Activated LED Stair Light with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wonder where your pet goes at night? With this kit, you’ll build a motion-activated LED strip that lights up the stairs for 30 seconds whenever your pet passes by. It’s a simple home automation project that brings safety and visibility to dark staircases, using an Arduino Uno and a PIR sensor.
What You'll Build
A reliable motion-triggered lighting system that mounts near your staircase. When the HC-SR501 PIR sensor detects movement, the Arduino Uno sends a signal to the 5V relay module, which turns on a set of white LEDs for exactly 30 seconds. The result: a warm, guiding light that helps your pet navigate safely, and alerts you to their activity.
What You'll Learn
- How to interface an HC-SR501 PIR motion sensor with Arduino Uno and calibrate it for pet-sized movement.
- Controlling a 5V relay module to switch a set of LEDs, and why the 1N4007 diode protects your circuit.
- Writing Arduino code to trigger a timed 30-second output after motion is detected.
- Assembling a stable circuit on a breadboard, using pull-down resistors for clean sensor readings.

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students working on computer science or physics projects, B.Tech ECE/EEE students exploring IoT and automation, and ATL Tinkering Lab tinkerers. With an age range of 5-15, it’s a perfect parent-child weekend project that introduces real-world sensor-actuator systems. It’s also great for Smart India Hackathon participants needing a quick prototype for pet safety or elderly care solutions.
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.
What if I get stuck during the build?
The AI companion, accessible via QR code on the box, guides you step by step. If you need human help, reach out on WhatsApp.
Can this kit actually detect my pet’s movement on stairs?
Yes, the HC-SR501 PIR sensor is sensitive to the heat signature of warm-blooded pets; with proper placement at stair height and adjusted delay, it reliably detects motion within a 3-5 metre range.
Will the relay be safe for switching just LEDs?
Absolutely, the relay is rated for 10A at 250V AC, but you’ll use it in DC low-voltage mode to switch the LEDs. The included 1N4007 diode protects against voltage spikes.
My child is 8 years old – can they build this?
With adult supervision, yes. The kit uses safe low voltages, and the breadboard assembly means no soldering. The AI companion provides visual guidance suitable for young learners.
