Road safety alarm

Description:
The Road Safety Alarm Working Model is an educational project designed to enhance road safety by alerting drivers and pedestrians to potential dangers. Using sensors and an alarm system, this model simulates real-world applications of safety technology to prevent accidents and promote awareness.

Key Features:

1. • Demonstrates a functional road safety alarm system.
   • Integrates sensors to detect potential hazards and triggers alarms.
   • Highlights the importance of safety technologies in reducing road accidents.

Materials Needed:

1. Foam Board or Sun Board: Base for setting up the model.
2. IR Sensor Module: Detects vehicles or pedestrians near the danger zone.
3. Buzzer: Emits an audible alarm to warn about potential hazards.
4. LEDs: Provides visual indicators for alert signals.
5. Relay Module: Controls the alarm activation.
6. Transistor: Works as a switch in the circuit.
7. Resistors: Regulates the flow of current.
8. Diodes: Protects the circuit from reverse currents.
9. PCB Board: Organizes and connects components.
10. Connecting Wires: Links all electronic components.
11. 9V Battery with Clip: Powers the system.

Working Principle:

  * Hazard Detection: The IR sensor detects the presence of vehicles or pedestrians near the danger zone.

  * Signal Processing: The sensor sends a signal to the relay and alarm system.

  * Alert Activation: The buzzer emits a sound, and LEDs light up to alert users of potential risks.

Applications:

1. • Demonstrates road safety concepts for students.
   • Simulates real-world applications like pedestrian crossings, sharp turns, or blind spots.
   • Encourages awareness about accident prevention and safety measures.

Conclusion:

The Road Safety Alarm Working Model is an engaging project that teaches students the importance of road safety technologies. By combining sensors and alarms, it effectively simulates real-world applications to enhance awareness and promote accident prevention.
