Auto Light Energy Saver Kit — Motion-Activated Light with Intrusion Timestamp Logging on Arduino

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

Energy waste from lights left on in corridors, storerooms, or even at home adds up fast. This kit lets you build a device that automatically switches on a light (or triggers an alarm) only when someone enters, and smartly logs the exact time of every motion event. You'll retrieve the logs later via a serial monitor — a foundational skill for security systems and smart energy management.

What You'll Build

A working prototype that turns on an LED indicator light when the PIR sensor detects human movement, while simultaneously storing the event timestamp (date and time) into Arduino's internal EEPROM using a DS3231 real-time clock. The red LED and buzzer can be programmed to activate as intrusion alerts, and the system can be extended to control actual appliances through a relay in future upgrades.

What You'll Learn

• How to interface a PIR motion sensor with Arduino to detect presence
• Programming the DS3231 RTC module to fetch accurate date and time
• Storing and retrieving data from Arduino's EEPROM for audit trails
• Building a simple serial monitor interface to read logged intrusion logs

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is perfect for CBSE Class 11–12 students working on science fair projects or ATL Tinkering Lab assignments on energy conservation. B.Tech ECE/EEE first-year students will find it a compact way to learn sensor integration and data logging for practical labs. It's also an ideal starter kit for young innovators participating in Smart India Hackathon junior challenges or building a school security system model.
