Square Analog output 24V US40 Serise Ultrasonic sensor

An ultrasonic sensor is a sensor that converts ultrasonic wave signals into other energy signals, usually electrical signals. Ultrasonic waves are mechanical waves with vibration frequencies higher than 20kHz. They have the characteristics of high frequency, short wavelength, minimal diffraction phenomenon, and excellent directionality, allowing them to propagate as directional rays. Ultrasonic waves have the ability to penetrate liquids and solids, particularly in opaque solids. When ultrasonic waves encounter impurities or interfaces, they produce significant reflections in the form of echo signals. Additionally, when ultrasonic waves encounter moving objects, they can generate Doppler effects.
