Project description In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to ...

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

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.

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

The JSN-SR04T Waterproof Ultrasonic Sensor As well as the familiar ultrasonic ranging module HC-SR04, another one seen on online markets is the JSN-SR04 (and variants). The JSN-SR04 ultrasonic ranging ...
