Many road accidents are due to drowsiness. To overcome this problem, we developed a new product called brain wave analyzer. This product contains a headband and analyzer box. The vehicle driver has to wear this headband while driving and the analyzer box has to be placed nearby. The analyzer box contains a microcontroller which monitors the driver's status. The brain waves of the driver are converted into digital value which indicates the drowsiness state of the driver. If it exceeds the safe limit, the analyzer box will start to alarm. So the driver can wake up from the drowsy state.
