Low-Cost Vehicle Security System
Designed around an ATmega8-16PI microcontroller and a Dallas Semiconductor iButton, this project is a cost-effective solution for vehicle security. An acceleration sensor is used to monitor motion. When motion is sensed, the system looks to see if the iButton is in place. If the iButton isn’t found, then an alarm sounds.
