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 HC-SR04 module includes ultrasonic ...

This Arduino project uses an HC-SR04 ultrasonic sensor to measure distance, a servo motor to sweep the sensor across a range of angles, and outputs status using a green LED, red LED, and a buzzer.

The objective of this project is to design and implement an Object Range Detection Sensor system using an ultrasonic sensor and Arduino Uno, as the core controller. This system aims to measure the ...

To do this, he used an ultrasonic sensor similar to, but cheaper than a Parallax Ping unit. Paired with an Arduino, the sensor triggers the fog machine’s pump for 20 seconds whenever anyone gets ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

Designed for short-range applications from 2" to 6", the RPS-400-6 ultrasonic sensor measures 0.75" x 2" x 1.5" and comes standard with integrated background suppression.

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 ...
