The smart water controller for metro water supply lines described in this work makes use of a relay, an ultrasonic sensor, a flow sensor, a solenoid valve, GPS, and GSM. The planned system is intended ...

An obstacle-avoiding robot using an ultrasonic sensor and motor control, programmed with Arduino to autonomously navigate and avoid obstacles by stopping, reversing, and turning.

The response of an integrating optical fiber (OF) ultrasound detector to varying sensor length and orientation with respect to the acoustic source has been experimentally investigated using Lamb waves ...
