distance sensor types
Distances sensors are devices that can measure the distance between an object and the sensor without touching the object. They are available in various forms, such as ultrasonic, laser, and optical sensors, in which each kind poses its own specific function & technical characteristics. The basic function of these sensors is to provide accurate distance measurement, data that is vital for many applications ranging from industrial automation to automotive safety systems. Functions vary, but they often include actual time measurement, high precision, and resistance to environmental conditions such as dust and moisture. For their applications distance sensors are used in robotics as part of obstacle avoidance systems; in manufacturing where they provide precise measurements; and parked cars too--automobiles use distance sensor technologies like this for parking aids.
