What is an ultrasonic sensor, and a comparison between optical and ultrasonic sensors 2

Optical sensors are sensitive to the color, transparency, and surface texture of objects. Transparent or highly reflective objects may interfere with measurement results, and optical sensors may exhibit different detection effects for objects of different colors.diode

4. Cost and implementation complexity:

Ultrasonic sensors: usually have lower costs, relatively simple implementation, and are suitable for cost sensitive applications.

Optical sensors, especially high-precision laser sensors, have higher costs and may require more complex designs in terms of algorithms and hardware.diode

In summary, ultrasonic sensors and optical sensors each have their own advantages and limitations, and are suitable for different application scenarios. The selection of which type of sensor to use depends on factors such as specific application requirements, environmental conditions, and cost budget. In practical applications, ultrasound and optical sensors are sometimes combined to leverage their respective advantages and achieve more accurate and reliable detection.diode
