AI-Based Accident Detection and Monitoring System Using YOLO, Accelerometer, and GPS

Road accidents cause over 1.3 million deaths each year around the world. Delays in getting help often make these situations worse, especially in far-off areas or fast-moving crashes where people can’t call for aid. This paper describes an IoT system that uses AI to spot accidents. It combines data from an accelerometer to measure sudden jolts, GPS to find the exact spot, and GSM to send quick messages. The setup runs on a microcontroller connected to an MPU6050 accelerometer and NEO-6M GPS. It checks sensors every 100 milliseconds and starts working if the G-force goes above 3g. It figures out the jolt strength with the formula e goes above 3g. It figures out the jolt strength with the formula (x2+y2+z2)/9.8\sqrt{(x^2 + y^2
