Ultrasonic sensor for measuring distance and detecting obstacles designed for STEM training, robotics and IoT projects. It uses ultrasound waves to accurately measure the distance to objects, which makes it suitable for building autonomous robots and intelligent systems.The sensor sendsultrasound signalwhich is reflected by its objects. By analyzing the received signal, it determines the distance with high accuracy, allowing reliable detection of obstacles and realization of functions such as automatically avoiding obstacles and navigating robots.Thanks to modular design of the systemPlanetX, the sensor is easily combined with other modules to create various educational and engineering projects. The color label of the ports facilitates proper connection and makes working with it easy for both beginners and advanced users.For the use of the sensor are necessaryNezha Expansion BoardandRJ11 cablewhich are offered separately.
