Description

The Laser Security System Working Model – Unassembled Kit is an engaging, hands-on educational tool that demonstrates the core principles behind a laser-based security alarm. Designed for students, hobbyists, and educators, this kit allows you to build a fully functional security system from scratch. By using a laser diode, an LDR, and a transistor-based sensor circuit, the model simulates how a real-world security system detects intrusions and triggers visual and audio alerts.

Features

• Interactive Assembly:
  Build your own laser security system using the provided components and follow the clear, step-by-step guide printed on the durable cardboard base.
• Practical Demonstration of Security Technology:
  The kit uses a laser diode to emit a beam that, when interrupted, causes the LDR to sense a change in light intensity. This change is processed by a transistor, which in turn activates a buzzer and an LED to simulate an alarm.
• Hands-On Learning Experience:
  Gain valuable insights into sensor technology, electronic circuits, and alarm systems. The project is ideal for exploring how simple components work together to create a responsive security system.
• Versatile Educational Tool:
  Perfect for classroom experiments, personal projects, or hobbyist exploration, this kit lays a solid foundation for understanding modern security systems and sensor-based applications.

What’s Inside the Box

• Cardboard Base with Printed Guide:
  A durable mounting board featuring a full assembly guide and wiring diagram to help you put the project together easily.
• Resistor:
  Essential for current limiting and ensuring the circuit operates safely and effectively.
• LED:
  Acts as a visual indicator by lighting up when the security system is triggered.
• Buzzer:
  Provides an audible alert to simulate the alarm function when the laser beam is interrupted.
• LDR (Light Dependent Resistor):
  Detects changes in light intensity when the laser beam is blocked, serving as the key sensor in the circuit.
• Laser Diode:
  Emits a focused laser beam that forms the security “tripwire” of the system.
• Free 3D Printed Parts:
  Custom-designed components to help mount or secure the circuit elements in a professional layout.
• Transistor:
  Amplifies the sensor signal from the LDR and drives the buzzer and LED when the beam is broken.
• Battery with Clip:
  Provides the power necessary to run the circuit, complete with a clip for easy connection.
