What Is a Smart Helmet with Accident Detection?

A Smart Helmet with Accident Detection is a safety device designed to monitor the rider’s motion and detect accidents using sensors. When an accident occurs, the helmet sends an alert message to emergency contacts through GSM and shares the GPS location. This makes it widely used in:

• • School projects

  • University projects

  • Industrial projects

  • Medical science model projects

  • IoT-based engineering projects

Why This Project Is Popular in Lahore

Students in Lahore often visit Hall Road electronics market searching for project ideas, components, and engineering support. Since this project uses:

• • Sensors

How the Smart Helmet Works

The helmet uses:

• • Accelerometer to detect sudden impact

  • Vibration sensor to verify accident force

  • Arduino to process signals

  • GSM module to send SMS

  • GPS module to track location

  • Bluetooth module for mobile app pairing

When an accident occurs, the sensors detect abnormal movement, and Arduino instantly sends an alert containing:

• • Rider’s name

  • Live location

  • Emergency warning

Required Components

Here is the complete parts list:

1. Arduino Uno or Nano

Acts as the main controller.

2. Accelerometer/GYRO (MPU5060)

Detects tilt, motion, and sudden impacts.

3. Vibration Sensor

Confirms whether the helmet has experienced a real crash.

4. GSM Module (SIM800L)

Sends an emergency SMS to family members.

5. GPS Module (NEO-6M)

Provides live coordinates.

6. Bluetooth Module (HC-05)

Allows settings configuration through a mobile app.

7. Power Supply

5V battery pack or Li-ion with a BMS.
