To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo ... sound like for anyone who has a bunch of these little Arduino-compatible modules lying around and has probably ...

or ambient-light contamination limit optical effectiveness. However, there are times when neither sensor will work. Fortunately, a third option does exist: the retroreflective ultrasonic sensor.

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a ... There might be a lot of very interesting observations coming to light then and I will ...

Because sensor operation uses sound waves rather than light, ultrasonic sensors provide an effective alternative to optical sensors in wet or dirty environments, as well as in applications where ...
