What is a Distance sensor?

A distance sensor is used to measure the distance to an object. These sensors typically use technologies such as ultrasound, laser, or infrared to calculate the distance to the target. Ultrasonic sensors use sound waves to measure the distance to the object, laser sensors utilize light reflection to calculate the distance, and infrared sensors measure the distance by reflecting infrared light. These sensors are widely used in various fields, ranging from industrial applications to automotive, robotics, and consumer electronics. As non-contact sensors, they are highly valued for their ability to measure distances accurately without directly touching the object or environment.

Application of Distance sensor

✅ Obstacle Detection in Robotics
Robots use distance sensors to detect and avoid obstacles. By employing ultrasonic or laser sensors, the robot can measure the distance to obstacles in real-time and move safely within its environment.
✅ Parking Assist Systems in Automobiles
In vehicles, parking assist systems utilize distance sensors to measure the distance between the car and surrounding objects. This helps drivers park safely, with ultrasonic sensors being commonly used for this purpose.
✅ Positioning in Industrial Machinery
In industrial machinery, precise positioning is required. Distance sensors are used to accurately measure the position of components or tools, improving the precision of production lines. Laser or infrared sensors are commonly used for this purpose.
✅ Face Recognition in Smartphones
In smartphones, infrared sensors are used for measuring the distance to a user's face, allowing for secure unlocking and user authentication. This enhances both security and convenience.
