Build a Working Home Security Alarm with the Arduino Uno 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.

Imagine walking into your room and an alarm lights up, beeping loudly to alert you — this kit makes that real. Using the HC-SR501 PIR sensor, your Arduino Uno will detect human movement and trigger red LEDs and a buzzer, creating a basic intrusion alert system you can mount by your door or window.

What You'll Build

You'll assemble a fully functional motion-triggered alarm module on a breadboard. The circuit lights up three red LEDs and sounds a buzzer instantly when someone moves within the sensor’s detection zone. It’s the perfect starter project to understand how real security systems work and can be expanded with a relay or wireless module later.

What You'll Learn

• Wiring a PIR sensor to Arduino and understanding its output signal
• Programming conditional logic to trigger alerts based on sensor input
• Using a breadboard to build and modify circuits without soldering
• Debugging basic electronics and reading component datasheets

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Perfect for young makers aged 10+ exploring Arduino for the first time, school students preparing science exhibition models, and beginners at ATL Tinkering Labs who want a quick, rewarding project that demonstrates sensor integration. It’s also ideal for CBSE Class 7-10 students and hobbyists building a foundation in electronics with a practical, real-world use case.

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.
