- Cable Ties × 1–2 (For Wire Management)
- All the design details are elaborated in documents with this.
Working Principle
The DIY Infrared Alarm Kit demonstrates light transmission and detection using basic electronics. A steady laser beam keeps the circuit inactive; however, when the beam is interrupted, the receiver stops sensing light and instantly triggers the alarm. This clear cause-and-effect mechanism makes the project an effective mega science kit for understanding sensors, circuits, and laser applications in security systems.Advantages of This Science Project
Quality Time Together: Build the system step by step and enjoy collaborative learning through a structured mega science kit experience.Learning Wrapped in Fun: The project turns electronics into an exciting challenge, offering learning depth comparable to a smartivity science kit while remaining practical for school use.
Confidence and Achievement: Completing the working alarm strengthens logical thinking, experimentation skills, and technical confidence.
