Accidental Detection IoT Sensor

Overview

A DIY compact ESP32-based Automatic Accident Detection System for motorcycles. On crash detection, it sends an SOS alert with exact GPS coordinates to an emergency contact via SMS.

Key Features

• ESP32 microcontroller processes sensor data in real-time
• MPU6050 6-axis gyroscope + accelerometer detects G-force spikes and tilt angle
• Neo-6M GPS locks onto satellites for precise coordinates at the crash moment
• A9G (GSM/GPRS) sends an SOS SMS with a Google Maps link
• False-positive filtering requires both high G-force and sustained tilt to avoid false alarms from potholes or stops
