Ultrasound distance sensor can be widely used in level monitoring, robot anti-collision, various ultrasonic proximity switches, and anti-theft alarm and other related fields. It is reliable, easy to install, waterproof, small angle of launch, high sensitivity, easy to connect with industrial display instruments, and also provides a probe with larger angle of launch.

Ultrasound has great penetration ability to liquid and solid, especially in opaque solids, which can penetrate tens of meters deep. When ultrasound touches impurities or interfaces, it will produce significant reflection and form echoes. When it touches a moving object, it will produce Doppler effect. Therefore, ultrasonic detection is widely used in industry, national defense, biomedicine and other fields.
