AN ULTRASONIC SENSORY-BASED DEVICE FOR REAL-TIME DETECTION OF TERRORIST THREATS USING ARDUINO-UNO

Abstract

In recent times, the Boko Haram sect and bandits have been ambushing people more often, inflicting mayhem to their victims. Detecting these criminals before the strike will go a long way to resolving some of the atrocities caused. An Arduino UNO board assembles the servo motor and the ultrasonic sensor using the C++ programming IDE software. The interaction of the Arduino using AT Mega microchip helps in coordinating and controlling the rotation of the servo motor, which aids the scanning of a target via an ultrasonic sensor from 0˚ to 180˚. This work was fashioned with an ultrasonic sensor mounted on a servo motor to give the 180˚ rotational scanning for targets. It was observed that the outcome of the tested result is about 98% accurate over a targeted radius ranging from 0m to 200m.
