The sensors attached to the Arduino had an approximate scanning range of 3m, and the ultrasonic units were modified to broadcast an analog signal at 40 kHz.

The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ...

Seeking students for projects prototyping a set of self-powered embedded sensor systems for pervasive computing. These projects will sharpen your hardware and software skills.

SJEC-AICTE IDEA lab in collaboration with Department of Electronics and Communication Engineering (ECE) at St Joseph ...

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, ...

His first video deals with using with ultrasonic sensors. He found an interesting white paper that described measuring airflow with a single-path acoustic transit time flow meter.
