Auto intensity control of street lights :
Basic purpose of this project is to make street lights intelligent so that it can turn it on and off itself. Another feature of this project is that street lights intensity vary according to intensity of light and number of vehicles on road. Followings are the main features of this project :
Street lights turns itself on automatically during night or darkness. They turn themself off automatically during day time and during visible intensity of light.
Street lights controls its intensity automatically according to intensity of light. For example in evening intensity of light start decreasing at the same time street lights start increasing its intensity. When there is no intensity of light in after evening, street lights turn themself on with full intensity till midnight at 12:00 am.
There is another feature included in this project that is vehicle detection. Infrared sensor circuit is used to detect vehicles on road. After 12:00am street lights start decreasing their intensity. At 1:00am street lights turn off automatically. After 1:00 am function of vehicle detection starts. If there is any vehicle on road after 1:00am, street lights turns on for 2 minutes. After that they turn off automatically. In other words, After 1:00am street lights turn on only if there is any vehicle on road. Otherwise they remain off. This process remains till morning. But after having visible intensity of light during moring street lights turn off automatically.
Advantages of auto intensity control of street lights :
As it name suggest suggests it makes use of street lights very easy. Some of the main advantages of them are given below:
No need to control street lights manually.
Electrical power saving.
Increases life time of street lights.
intelligent street lights.
vehicle detection.

Followings are the main components of auto intensity control of street lights. I have explained all these components and their functions briefly.
