The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

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.

I have seen too many posts highlighting the erroneous distance reports of the HC-SR04 ultrasonic sensor module. In principle, it can “conditionally” detect the distance of objects between 2 and 400 ...

An ultrasonic sensor emits sound waves to measure the distance of potentially hazardous objects. The cane can then vibrate to alert its user. (Nick Boisvert/CBC) ...
