Arduino Trespassing Detector with Timestamp Logging - Build a DIY Security System That Remembers

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 a security device that not only sounds an alarm when someone enters a room but also secretly writes down the exact time it happened. You'll assemble that very system-a PIR sensor to detect motion, a real-time clock to timestamp every trigger, and Arduino code that stores the log permanently. Later, plug it into a laptop and retrieve a complete intrusion history, just like a real security system.

What You'll Build

A standalone unit that flashes red LEDs and lets out a sharp beep the moment movement is sensed, while quietly recording the event with a precise date and time. Connect it to any computer via USB, open the Serial Monitor, and you'll see a neat list of every triggered moment. It's your own little security guard that remembers when someone trespassed.

What You'll Learn

• Programming an Arduino to detect motion with a PIR sensor and capture real-time clock data
• Reading and writing timestamp logs to the microcontroller's EEPROM for permanent storage
• Retrieving logged data via serial communication and displaying it in a readable format
• Assembling and testing an electronic alarm circuit with visual and audible alerts

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students exploring embedded systems and sensor integration, ATL Tinkering Lab participants building a working security prototype, and B.Tech ECE/EEE students looking for a hands-on project to understand data logging and real-time clocks. Smart India Hackathon teams can use it as a rapid proof-of-concept for security monitoring. Even young hobbyists (age 10+) can build it with parental guidance, sparking an interest in electronics and programming.

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.
