This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose ... The set-up process is very simple, ...

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, it then sends a signal to the Arduino UNO, which ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic ... of the sweeping sensor, a missile is fired using the dart launcher. It’s a relatively simple build, but ...

[Eduard] chose the latter, and also included obstacle avoidance sensors in the process. We’ve seen quite a few that use these ultrasonic rangefinders. He decided to go a different route by ...

As a 3D ultrasonic sensor, Sonair works very differently, enabling it to provide safe, fast and effective obstacle detection using ... higher energy consumption. Simple, 1D ultrasonic sensor ...

Now, researchers have channeled that idea to create an ultrasonic sensor ... on down to the shins. Each sensor constantly scans the environment using ultrasound to detect anything closer than ...
