A flexible and wearable ultrasonic sensor (WUS) constructed from a piezoelectric polymer film has been proposed for long-term continuous monitoring of the artery motion. The non-focused plane-wave ...

Gesture-based home automation allows users to control household devices through simple hand movements, removing the need for switches or remotes. It improves convenience, accessibility, and hygiene ...

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 ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...
