Flexible Light Intensity Control of Headlamp and Health Monitoring System

Accidents are termed as unplanned event which causes serious damage to life and property. The reason for road traffic accidents may vary but the major reason is due to driver's ill-health and inattention. A prototype is designed for continuously monitoring the driver's current health condition and automatic headlight intensity control. For adaptive light intensity control, the system will continuously monitor the opposite vehicle's headlight intensity. If the opposite vehicle intensity is high, the headlight beam will be lowered and vice versa. Depending upon the approaching vehicle headlight intensity, the vehicle headlight beam will be either lowered or raised. This avoids glare for the approaching vehicle driver and ensures a safe drive. This anti-glare system will avoid accidents due to unclear vision or temporary blindness due to headlamp light intensity. Another main reason for accidents is the driver's health abnormality. It causes threats to the people traveling in the vehicle and to the people in the approaching vehicle. This system will continuously monitor the main health parameters of the driver like heart rate and temperature. The alcohol is also sensed by the gas sensor. These sensors are interfaced with a microcontroller and the values are compared with the predefined values. The status is displayed in the LCD and information will be provided to the owner through SMS.
