Makers, Arduino enthusiasts and students looking to learn more about ultrasonic sensors, may be interested in this DIY Arduino radar created by Mr Innovative. Capable of detecting objects placed in front of it the radar features a revolving dish capable of detecting objects in its line of sight. Watch the video below to learn more about its features, construction and capabilities.
Mr Innovative explains more about the project and some of the components included in it. “Hello friends in this video I have made a Mini compact Radar with display, for that I have used HC-SR04 ultrasonic sensor, this sensor emit ultrasonic sound which came back to sensor after reflecting from an object, all the data visualization is displayed on 1.8″ ST7735 display, if any object detect by radar it’ll show in display in red line.”
“Ultrasonic sensors emit a high frequency sound wave then listen for its return to determine an object’s distance, are useful in a wide variety of robotics projects. If you’d like a visualisation of how the sensor views an area, this “radar” from Mr Innovative presents a fun option.”
