This project presents an automatic vehicle accident detection and alerting system using GPS and IOT modem. GPS receiver, ADXL335 accident sensor, LCD, Buzzer and an esp8266 wi-fi module is interfacing to the PIC Microcontroller. Microcontroller will continuously monitor the vehicle location from GPS module and sending this location to the user mobile through esp8266 wi-fi module in the form of latitude and longitude values and display the same data on LCD. Whenever accident sensor detects the vehicle accident microcontroller will take the location of the vehicle from GPS and sending this location along with alert intimation to the user mobile application through IOT and also activate the buzzer for alerts. The status of the project will display on LCD.  

Features:

• IOT based continuous monitoring of vehicle location and accident alerting system.
• GPS based location Identification.
• Sending location in the form of latitude and longitude.
• Adxl345 sensor for Accident detection.
• Automatic accident detection and alerting system.
• Visual alerts using LCD.
• Audible alerts using BUZZER.
