Speeding Detection System
Team Information

ECE4180, Section B
Description
The Speeding Detection System is designed to track a driver's speed and notify them when they cross a certain speed or when they are driving unsafely. The system records when a violation occurs for later viewing by anyone interested. GPS is used to calculate the speed a driver is moving by using two longitude and latitude measurements. An accelerometer is used to detect sharp turns. When a driver crosses a certain speed or turns too sharply, a speaker plays a warning and a time stamp is recorded onto an SD card.
