The difference in performance between ultrasonic and laser range finder

1. Accuracy: The measurement accuracy of ultrasonic range finder is centimeter level, and the measurement accuracy of laser Distance Measuring Sensor is millimeter level;

2. Measurement range: The measurement range of the ultrasonic range finder is usually within 80 meters, while the measurement range of the hand-held laser range finder is up to 200 meters, and the measurement range of the laser ranging telescope is up to several hundred kilometers. Even further.

3. Error probability: The ultrasonic range finder is easy to report errors. The main reason is that the ultrasonic range finder/ranging sensor is a sound wave emission and has the fan-shaped emission characteristics of sound waves. Therefore, when the sound wave passes through more obstacles, the reflected sound waves are more More, more interference, easy to report errors, and the Laser Ranging Sensor is a very small beam of lasers emitted back and forth, so as long as the beam can pass, there is almost no interference.

4. Price: The price of ultrasonic range finder is from tens of yuan to several hundred yuan. The price of laser range finder varies from several hundred yuan to several thousand and several tens of thousands. According to the difference of precision and distance, there is a big difference.
