REG670 Principle and application of ultrasonic sensor
REG670Working principle of ultrasonic sensor Ultrasonic sensors work on the principle of sound wave reflection in physics. It works like a radar system, but instead of electromagnetic waves, it uses sound waves with frequencies higher than the range of human hearing (usually above 20kHz, typically around 40kHz). It emits high-frequency ultrasonic pulses (usually in the…
