Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that ...

Abstract: Recently, passenger vehicles were equipped with an Advanced Driver Assistance System (ADAS) feature in assisting drivers to control the vehicle, which gives an alarming signal about possible ...

Abstract: Ultrasonic waveguide techniques are most familiar to monitor temperatures in the hostile environments. A single waveguide could be used as multiple sensors. In the present work, a thin strip ...
