Radar sensors are devices that use radio waves to detect and locate objects. They emit signals that bounce off objects and return to the sensor, allowing it to determine the distance, speed, and direction of the object. This technology is commonly used in various applications, including automotive safety systems, air traffic control, and weather monitoring. These sensors can operate in different weather conditions and are not affected by light, making them reliable for both day and night use. Radar sensors are essential for enhancing safety and efficiency in transportation, as well as for gathering data in scientific research.
