Piezoelectric ultrasonic horn sounds outside the hearing range of the human ear, that is, at frequencies above 20KHZ. Mainly used in driving birds, driving dogs, driving mice and other fields, through the TS, IATF and other certification. If necessary, please contact Amy：+86-519-89185720. or norr@manorshi.com
FAQ:
How do ultrasonic sensors work?
Ultrasonic sensors are devices that convert ultrasonic signals into other energy signals (usually electrical signals) to measure distance from the sensor to the target object. Ultrasonic wave is a mechanical wave with a vibration frequency higher than 20KHz and it has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally.

How to use ultrasonic sensor with Arduino?
HC-SR04 is a very popular sensor for measuring distance. It emits ultrasonic waves at a frequency of 40KHz. The ultrasonic waves travel through the air. If there are objects or obstacles in the path, it will bounce back to the module. Taking into account the propagation time and the speed of sound, you can calculate the distance. Read more
What is Ultrasonic ranging sensor?
Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasonic ranging sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasound is a mechanical wave with a vibration frequency higher than 20kHz. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, and can be ray and directional propagation.
Ultrasound has a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. Ultrasonic waves encountering impurities or interfaces will produce significant reflections to form reflected echoes, and touching moving objects can produce Doppler effect. Ultrasonic sensors are widely used in industry, national defense, biomedicine, etc. Read more
