In today's busy world, the rate of accidents are tremendously increasing.The studies have found that 40% of accidents happen during night and the major reason for the occurrence of accidents that happen during night is the glare that results from the high beam intensity headlight that vehicles put on. The high beam headlight is actually meant for illuminated vision during night rides where there are no other vehicles nearby and the low beams are meant for a clear path any time during night even when there are vehicles around.The high beam intensity headlight painfully blinds the driver and creates heavy glare which makes vision impossible.That is, even if the driver couldn't change the beam intensity as and when required, the sensor in the vehicle automatically understands when is it required to change the intensity and alters accordingly.In this way whenever two vehicle approaches to each other, the beam intensity of both the vehicles becomes dim simultaneously which helps for better driving anytime.The circuit consists of a package of programmable Arduino, a PIR Sensor, power source, LDR and the supporting headlight.Whenever there encounters any presence of light above 1 candela of light intensity on the sensor the resistance of LDR decreases which eventually decreases the voltage across LDR.In this way the sensor in the controller circuit senses the presence of any intensity of light and turns the high intensity headlight automatically to low intensity beam.PIR which is typically a motion sensor senses the motion of vehicles that passes from at a distance of 50meters.

In today's busy world, the rate of accidents are tremendously increasing. The studies have found that 40% of accidents happen during night and the major reason for the occurrence of accidents that happen during night is the glare that results from the high beam intensity headlight that vehicles put on. The high beam headlight is actually meant for illuminated vision during night rides where there are no other vehicles nearby and the low beams are meant for a clear path any time during night even when there are vehicles around. It is to be followed that whenever you see a vehicle in front, your high beam headlight should be lowered in order to reduce its impact on the driver of opposite vehicle. But people often forget to dim their headlight when a vehicle approaches them. The high beam intensity headlight painfully blinds the driver and creates heavy glare which makes vision impossible. The driver looses his control and results in dreadful accidental situations. This very crucial problem which is one of a major headache to the society can now be avoided by making use of 'Automatic Headlight Intensity Controller'. In this way the sensor in the controller circuit senses the presence of any intensity of light and turns the high intensity headlight automatically to low intensity beam.
The circuit consists of a package of programmable Arduino, a PIR Sensor, power source, LDR and the supporting headlight. PIR which is typically a motion sensor senses the motion of vehicles that passes from at a distance of 50meters. The Arduino is programmed in such a way that whenever it encounters the presence of light, the connected LDR senses this illumination and reduces the high beam to low beam when it is at the high beam. The program is made to make the default setting of headlight as high beam. The sensor can also detect the presence of light of the street light and also the light from the nearby shops which male it function the same way if the intensity is greaterthan 1 candela. Whenever the road is free of light the sensor senses no light and thus the headlight remains in high beam state. Whenever there encounters any presence of light above 1 candela of light intensity on the sensor the resistance of LDR decreases which eventually decreases the voltage across LDR. This results in lowering of light intensity of the headlight to low beam. When this technology is installed in all the vehicles, it is sure that this can bring a novel change to the society. That is, even if the driver couldn't change the beam intensity as and when required, the sensor in the vehicle automatically understands when is it required to change the intensity and alters accordingly. In this way whenever two vehicle approaches to each other, the beam intensity of both the vehicles becomes dim simultaneously which helps for better driving anytime. We already know how much disturbing is the high beam headlight intensity of an opposite vehicle. If we see an opposite vehicle with high beam headlight it doesnot mean that we are free to do that as well. If you think someone else's headlight is hurting
