Traffic Light Sensor

A traffic light sensor is an electronic device used to detect vehicles, pedestrians, or changes in traffic conditions and provide information to a traffic control system. It can work with sensors such as ultrasonic, infrared (IR), or cameras to detect the presence or movement of objects. A microcontroller like Arduino can process the sensor data and control traffic lights accordingly. Traffic light sensors are commonly used in smart traffic management systems, pedestrian crossings, vehicle detection, and automated traffic control projects.
