Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

A low-power ultrasonic flow-sensing module from ScioSense brings multi-year battery life to industrial and consumer ...

Unlike traditional mechanical sensors, the UFM-02 uses ultrasonic technology without turbines or moving parts, which ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

Ultrasound refers to any audio signal above the range of human hearing. Generally that’s accepted as 20 kHz and up. Unlike electromagnetic signals, ultrasonics are still operating in a medium – ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

Struggling to measure flow without using much battery power? This module uses low power, measures flow, and can detect small ...

[Lindsay] has a wonderful writeup about a new toy in the shop, an ultrasonic transducer. The 28kHz, 70W bolt-clamped Langevin transducer by itself is not much use, you need a power supply, a horn to ...

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 ...
