The digital EV3 Ultrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects.
It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program.
This LEGO Mindstorms EV3 Education ultrasonic sensor allows you to study and discover how this type of technology is used in our daily lives. Automatic doors, cars, production lines: every real use of an ultrasonic sensor can be reproduced in the classroom. A group of students can, for example, create a road traffic monitoring system by measuring the distance between vehicles.
