Arduino - Radar/Ultrasonic Detector

The detector is a device measuring device that reveals the existence of a phenomenon or object. In today branches of science used for observation of the phenomenon, the separation of a signal or as in this paper for search and detection of objects. Most commonly used in chemistry, radio technology, physics and as a metal detector. The chemistry is a device used to detect the presence of substances (often toxic or harmful). The radio technology detects signals of higher frequency converting AC to DC signal. In physics, a device for determining the properties or identifying particles and radiation. The aim of this project was the realization of detectors facilities with two-dimensional representation of registered objects on the LCD screen. The project is based on the Arduino microcontroller, an ultrasonic sensor HC-SR04 and serial communication between the two devices to a computer. The mere communication of microcontrollers and sensors today is one of the ever-present detection method and calculating the distance of objects. The servo motor is used to start the ultrasonic sensor. Programming is determined swing angle servo motor from 15º to 165º. Ultrasonic sensor, which normally measures the distance to 4 m, in this project is configured to measure the distance up to 40 cm.”
