HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using ...

The ultrasonic sensor module HC-SR04 is a popular and cheap: (<; $2) per unit; it is, mainly, used and designed for distance measurement. In this article, a time space framework for a linear array of ...

Ultrasonic Sensor Explorer (USE) is a cheap mobile robot for mapping. Instead of expensive laser sensor, it uses cheap ultrasonic sensor HC-SR04 with range up to 4 meters.

Experimental data on the free fall of a plastic box through the air was gathered with the help of an ultrasonic distance sensor (HC-SR04). Readings were taken at different intervals during the fall to ...
