Heading: HC-SR04 Ultrasonic Distance Sensor Module
Product Overview:
The HC-SR04 Ultrasonic Sensor Module is an essential, easy-to-use component for precise, non-contact distance measurement. Perfectly suited for electronics hobbyists, STEM students, and robotics developers, this module uses sonar to determine the distance to an object, mimicking the way bats navigate.
Whether you are building an obstacle-avoiding robot, a digital tape measure, or a smart parking assistance system, the HC-SR04 provides stable performance and high accuracy in a compact design.
Key Features:
Precise Measurement: Offers high accuracy with a detection range from 2cm up to 400cm (4 meters).
