IOT Based Smart Helmet for Road Accident Detection

The IoT-based Smart Helmet is a revolutionary safety solution designed to detect accidents and provide immediate alerts in case of emergencies.This innovative helmet integrates advanced hardware components including the ESP32 microcontroller, MPU6050 accelerometer, switch, buzzer, SIM800 GSM module, and GPS sensor.Combined with Arduino IDE and C++ programming, this system ensures seamless operation and reliable performance.Under normal conditions, the MPU6050 accelerometer continuously monitors the helmet's orientation and movement, providing stable signals.However, in the event of an accident, such as a fall, sudden impact, or collision, the accelerometer detects the abrupt change in coordinates, triggering an alarm through the buzzer.Upon activation of the alarm, the user has the option to stop the buzzer by pressing the switch if they are unharmed.Conversely, if the user is severely injured and unable to move, the buzzer continues to sound persistently.After a predefined period, typically 5 minutes, the system automatically initiates the SIM800 GSM module to send SMS alerts and make calls to predefined contacts.Simultaneously, the system retrieves GPS coordinates from the GPS sensor, providing accurate location information of the user's position.These vital details are transmitted along with the distress signals, ensuring prompt assistance and rescue operations.In the event that a bystander or rescuer intervenes and activates the switch, the system resets, returning to its initial state to resume monitoring and protection.This intelligent safety mechanism aims to save lives by swiftly alerting emergency responders and providing crucial location data, ultimately enhancing user safety and security.
