If you have played with ultrasonic distance measurement projects, I’m sure you have at some point played with the HC-SR04 Ultrasonic sensor modules. Shifting to the new waterproof ultrasonic sensor is ...

The paper presents a system based on an ultrasonic emitter and two ultrasonic receivers which can locate more precise an object located in their detection range, being able to measure the distance to ...

Several types of equipment and approaches namely sensors, Computer Vision (CV) methods, micro-controllers etc. are used for detecting obstacles in the path. To enable an utmost collision free mobility ...

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.
