Vehicle Accident Detection System with LPWAN Technology for Information Transmission

This system is designed to monitor vehicles and provide information about their position and movements, par- ticularly in the event of an accident. The system can detect factors that commonly contribute to accidents, such as changes in speed, tilting, and collisions. The data is collected from three types of sensors: the ADXL 345 accelerometer, the tilt sensor, and the crash collision sensor. The system uses LoRa communication technology, which is affordable and easy to implement. To test the system's performance, LoRa modules were tested under two conditions: Line of Sight (LOS) and Non-Line of Sight (NLoS). The tests used a spreading factor between 10-12 and a bandwidth of 125 kHz and 250 kHz. The results showed that the data from the sensors accurately reflected the measurements taken by the transmitter device on the receiver device.
