Over speed has been a major problem in traffic and almost all accidents occur because of over speed. Even if strict laws are there vehicle owners neglect these rule. The policemen usually uses a radar to identify the over speed. But radar is very expensive. Using microcontrollers we can make efficient over speed detector which can even take snaps of the suspected vehicle which will help police to identify the over speeding vehicle
With the help of sensors , the microcontroller will detect the over speeding vehicle and will trigger the webcam to take a snap. The taken picture is then saved to a pc. We are using LDR as sensors here . For fast response and clear images we can use digital cameras with good storage capacity. Here an LED is used instead of camera for convenience.
