✅ Introduction

Road accidents are one of the leading causes of death globally. In many cases, victims do not receive timely medical assistance due to delays in accident reporting. An Accident Identification and Alerting System solves this problem by automatically detecting a crash and sending alerts to emergency contacts or authorities.

This project integrates sensors, microcontrollers, and communication modules to recognize accidents in real time and instantly notify responders with critical location data.

🔧 How the Accident Identification System Works

1. Continuous Monitoring

The controller reads real-time data from sensors to identify sudden impacts or abnormal tilting of the vehicle.

2. Accident Detection Logic

Using threshold values:

• High acceleration peaks
• Sudden orientation changes
• Vibration spike

If values exceed predefined limits, the system classifies it as a crash.

3. GPS Location Fetching

The GPS module quickly gathers the exact coordinate of the vehicle.

4. Emergency Alert Transmission

An automatic alert is sent through:

• SMS
• Phone call
• IoT dashboard
• Cloud notification

The message typically contains:

“Accident detected! Location: https://maps.google.com/?q=LAT,LON”

5. Local Alarm

A buzzer alerts nearby people for immediate help.
