Arduino Tutorial: Understanding Ultrasonic Sensors
Complete Video
The ultrasonic sensor is an input module that provides excellent non-contact distance detection, stable performance, ease of use, a small blind spot, and high accuracy. The measuring distance ranges from 2 centimeters to 400 centimeters, and the best part is that it is very inexpensive. It is widely used in the maker community, including applications such as robot distance measurement and obstacle avoidance, as well as liquid level detection.
