That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

It’s a motion controlled desk lamp that uses ultrasonic sensors to control its physical position. The core of the project is an Arduino and the three ultrasonic sensors.

For the physical feedback, Denver has made some vibrating boxes that you put in your pockets. An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the ...

A new ultrasonic fingerprint sensor measures 3-D image of your finger's surface and the tissue beneath it -- enhancing biometrics and information security for smartphones and other devices ...

Ultrasound sensor can fortify fingerprint scanners and how we measure our waistlines, according to scientists at the University of California.
