Keyestudio SR01 Ultrasonic Module V2 is a very affordable proximity/distance sensor that has been used mainly for object avoidance in various robotics projects. It uses upgraded N76E003AT20 solution.
It essentially gives your Arduino eyes/spacial awareness and can prevent your robot from crashing or falling off a table. It has also been used in turret applications, water level sensing, and even as a parking sensor.
This simple project will use the SR01 ultrasonic module V2 with an Arduino and a processing sketch to provide a neat little interactive display on your computer screen.
