Ultrasonic Transducer Transmitter Driver Circuit

Distance measuring is based on firing pulse and measuring the flight time of sound waves. We clearly know that ultrasonic transducers are driven with 40kHz PWM signal. Continuous PWM signal will not satisfy the conditions of distance measuring. Hence, we…

Ultrasonic Transducer – Transmitter & Receiver

a pair of transducers

Ultrasonic Transducer Ultrasonics sensors are used for anti-collision safety, object detection, park sensors and more. For developing special kind of ultrasonic system to solve a problem, we should understand the working, driving and receiving principle of the ultrasonic transducers first.…
