An ultrasonic sensor is employed to detect motion or human presence near the entry point, serving as the system’s initial trigger for activation.

In addition, these malicious signal injections into the ultrasonic sensors do not require sophisticated equipment, making it simple to stage a jamming or spoofing attack. This means that, in practice, ...

This paper introduces a pioneering approach to ultrasonic-based distance measurement using ultrasonic sensors. Recognizing the influence of diverse weather cond ...
