HC-SR04 Ultrasonic Sensor Acrylic Bracket

Give your HC-SR04 ultrasonic distance sensor a secure, professional mount with this precision-cut acrylic bracket. Designed specifically to cradle the HC-SR04 module’s dual sensor eyes, it holds the sensor firmly in place while keeping both transducers fully unobstructed for accurate distance readings, an important detail since even slight misalignment or blockage can affect measurement accuracy.

Made from durable acrylic with a clean, attractive finish, this bracket is a popular accessory for robotics builders working on obstacle-avoidance robots, smart cars, line followers, and other Arduino or ESP32-based automation projects. The sensor simply slots into the bracket’s circular holders with a light press fit, while two mounting holes let you fasten the assembly onto a chassis, panel, or 3D-printed frame using standard M3 screws (screws not included).

This bracket is a small but essential upgrade for anyone tired of taping or zip-tying sensors to their robot frame. It keeps wiring tidy, improves mechanical stability during movement, and gives your build a cleaner, more finished appearance. A must-have addition alongside any HC-SR04 module for makers building mobile robotics platforms or fixed-position ranging setups.
