Distinctive Excellence
Driver
Alert System
The
affordable Driver Alert System uses ZigBee accelerometer sensors
to monitor the movements of a motor vehicle driver’s head. The
LPC2138 microcontroller-based system is designed to predict
when a driver is falling asleep. Various audio alarms sound
to warn the driver. The alarm system performs three types of
warnings: it plays a loud, irritating noise through a Keil MCB2130
evaluation board’s on-board speaker; it plays customized prerecorded
messages (e.g., “Wake up!”); and it turns up the volume of the
vehicle radio.
