HC-SR04 Ultrasonic Sensor Bracket - Acrylic Mounting Holder

The HCSR04-Bracket is a precision-made mounting holder designed specifically for the HC-SR04 ultrasonic distance sensor module, providing a stable and repeatable mounting solution for robotics, smart vehicles, and DIY electronics projects. The bracket is cut from high-quality acrylic (plexiglass) with a body thickness of 2.8 mm to 3.1 mm, offering a balance of rigidity and low weight while resisting wear, impact, and typical environmental exposure better than standard plastics. Its 16 mm inner diameter accommodates the HC-SR04 transducer housings precisely, and the 3.8 mm mounting holes allow fastening to chassis, servo horns, and custom frames with standard M3 hardware. The dedicated design eliminates the wobble and angle drift that plague improvised sensor mounts, helping preserve measurement accuracy and data repeatability. When paired with a servo, the bracket enables environmental scanning across a 90° to 180° arc, which is valuable for obstacle-avoidance robots, path-finding platforms, and environmental monitoring systems. This HC-SR04 bracket is compatible only with the HC-SR04 module, and its purpose-built geometry ensures a snug, backlash-free fit. Whether the goal is to upgrade a robot chassis, build a distance-measuring station, or add reliable obstacle detection to a smart car, this ultrasonic sensor bracket offers a practical, low-cost, and mechanically sound mounting interface.

Application

1. Obstacle-avoidance robots and smart car platforms requiring stable ultrasonic sensor alignment.
2. Servo-mounted scanning heads for 90° to 180° environment mapping and distance measurement.
3. Line-following and path-finding robots that depend on repeatable sensor readings.
4. Educational electronics kits, DIY distance meters, and parking-assist prototypes.
5. Custom robot chassis and 3D-printed frames using standard M3 mounting hardware.
