The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

This module is usually built with the H2010 optical slot sensor (10mm Gap & 1mm Aperture). Note that some modules do not have the power indicator LED and the 10KΩ output pullup resistor! Finally, as ...

Ultrasonic sensors are already widely used in automotive applications and a variety of industrial applications. Now, though, new potential applications are being discovered in the home-automation ...

A single sheet placed between the emitter receiver pair attenuates the ultrasonic signal. For example, a single metal foil sheet can reduce audio intensity up to 80% at the receiver.

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 ...
