An enhanced obstacle detection system with a intelligent YJD1602A liquid crystal display (LCD) based on the Internet-of-Things (IoT) with electronic alarm system which incorporated a 25-Watt audio amplifier have been proposed development, constructed and tested as detailed in this paper. The obstacle detection is accomplished using HC-SR04 ultrasonic sensor while the IoT technologies are achieved through an Arduino Mega 2560 development platform. The performance of the proposed enhanced obstacle detection system have been verified as it has been able to measure and display the distances of objects (obstacles) with range from 0 to 4 meters with simultaneous triggering of the electronic alarm system when an object is detected while the alarm is off when no object is detected. The proposed EOD system can be adapted and deployed for obstacle detection and avoidance system design for robotics and mechatronics applications.
