This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics of ...

These are the type of flow meters that measure the velocity of liquid or gas by using the principle of ultrasound or sounds waves. Fast digital signal processors and sophisticated signal analysis ...

Ultrasonic sensors use sound waves above 20 kHz to measure the distance from the sensor to a specified target. The sensor transmits and receives sound via a ceramic transducer that acts like a ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

In-display fingerprint sensors have become commonplace in virtually all Android smartphones, for better or for worse, and five years later we’re finally seeing the ultrasonic variety widely used by ...

Ultrasonic sensors can measure distance without contact. can measure distance without contact. They bridge the gap between proximity and photoelectric sensing. They possess a longer sensing distance ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...
