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.

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

It’s an Arduino controlled “RADAR” like project that uses the familiar Parallax ultrasonic sensor.

As many Arduino enthusiasts will tell you, they have a million ideas for projects but haven't completed nearly as many as they want. Here are some of the best Arduino projects we have found.

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, ...

The sensor operates in harsh industrial environments and can be used in autonomous mobile robots and autonomous guided vehicles. The starter kit comprises a demo board with a USB-A to micro-B cable ...
