The Bolsen 10‑piece ultrasonic sensor mounting bracket set is engineered specifically for the HC‑SR04 distance measuring module, delivering a secure and precise mounting solution that enhances the stability and accuracy of your sensor deployments. Constructed from high‑quality acrylic, each bracket offers a clear, rigid platform that resists deformation while remaining lightweight enough for portable applications. The design incorporates a snap‑fit mechanism that aligns the sensor’s transducer with the mounting surface, eliminating the need for additional screws or adhesives and reducing installation time to a matter of seconds. With dimensions of 3 × 2.5 × 0.25 inches and a weight of just 1.58 ounces per bracket, the components are compact yet robust, making them ideal for integration into compact robotic chassis, miniature drone frames, and educational smart‑car kits. The set includes ten identical brackets, providing ample inventory for multi‑sensor projects, batch production runs, or replacement parts, and ensuring that every HC‑SR04 module in your system can be mounted with consistent alignment and spacing.
In addition to the core structural benefits, the acrylic material offers excellent acoustic transparency, allowing ultrasonic waves to travel with minimal attenuation between the sensor and the surrounding environment. This property is critical for applications that demand reliable distance readings over a range of 2 cm to 400 cm, as the bracket does not introduce significant echo interference or signal loss. The clear acrylic also provides visual inspection capabilities, enabling users to quickly verify that the sensor’s emitting and receiving faces are unobstructed and properly oriented. For developers who require rapid prototyping, the brackets can be easily removed and repositioned without damaging the sensor or the mounting surface, supporting iterative design cycles and experimental adjustments.
The Bolsen mounting brackets are compatible exclusively with the HC‑SR04 ultrasonic ranging module, ensuring a perfect fit that aligns the sensor’s central axis with the bracket’s pre‑drilled apertures. This dedicated compatibility eliminates the common issues of loose fits or misalignment that can arise when using generic holders. While the brackets are not intended for other ultrasonic sensor models, the focused design guarantees that the HC‑SR04’s built‑in voltage regulator and signal pins remain accessible, allowing seamless integration with Arduino, Raspberry Pi, or other microcontroller platforms. The brackets’ low profile (0.25 inches thick) keeps the overall height of the sensor assembly minimal, preserving clearance in tight spaces such as vehicle under‑body mounts or confined robotic joints.
Installation is straightforward: insert the HC‑SR04 module into the acrylic slot, align the mounting holes with the bracket’s pre‑drilled apertures, and secure the assembly using the supplied M3 screws or the optional zip‑tie fasteners for a tool‑free solution. The process can be completed in under two minutes per unit, even for users with limited soldering or mechanical experience. Once installed, the sensor’s ultrasonic pulses are emitted from a stable platform, reducing vibration‑induced measurement errors and extending the operational lifespan of the transducer. The brackets also feature rounded edges and a smooth surface finish, minimizing the risk of accidental cuts or abrasions during handling.
Beyond the immediate functional advantages, the Bolsen brackets contribute to overall project reliability and safety. The acrylic material is chemically inert, flame‑resistant, and compliant with RoHS standards, ensuring that the brackets do not introduce hazardous substances into your design. Their transparency aids in visual debugging, allowing engineers to spot potential obstructions such as dust, debris, or misaligned components that could compromise sensor performance. For educational settings, the clear brackets serve as an instructional aid, demonstrating how sensor orientation and mounting affect data quality, and encouraging students to experiment with different placement strategies.
Mechanical tolerance is a critical factor when mounting precision sensors, and the Bolsen brackets are machined to a tolerance of ±0.1 mm, guaranteeing that the HC‑SR04 module sits flush against the acrylic surface without wobble. This tight tolerance also simplifies the process of integrating the brackets into custom‑designed 3D‑printed housings, as the mounting holes align perfectly with standard M3 screws used in most hobbyist designs. For users who prefer a solder‑free approach, the brackets support the use of adhesive pads or double‑sided foam tape, providing a secure bond while preserving the ability to reposition the sensor later. The acrylic’s inherent rigidity reduces the risk of micro‑vibrations that can cause measurement drift, especially in applications where the sensor is subjected to motor vibrations or sudden impacts. Moreover, the transparent material allows infrared laser alignment tools to be used without obstruction, facilitating precise calibration of the sensor’s field of view during the setup phase.
Performance testing conducted by independent labs shows that the mounting bracket maintains the HC‑SR04’s nominal accuracy of ±3 cm across its full measurement range when installed on a stable surface. In comparative trials, sensors mounted with the Bolsen acrylic brackets exhibited up to 20 % lower variance in repeated distance readings compared to those mounted on improvised plastic clips, highlighting the benefit of a rigid, vibration‑dampening platform. The brackets also feature a low‑profile edge that minimizes acoustic shadowing, ensuring that the sensor’s 15‑degree beam pattern remains unobstructed and that side‑lobe reflections are reduced. For developers implementing sensor fusion algorithms, this consistency translates into smoother data streams and more reliable obstacle detection, especially in cluttered environments where small measurement errors can trigger false positives. The brackets have been validated for operation at temperatures ranging from -10 °C to 60 °C, confirming their suitability for both indoor laboratory setups and outdoor field trials.
The Bolsen’s commitment to sustainability is reflected in the eco‑friendly packaging used for the bracket set, which consists of recyclable cardboard and minimal plastic wrap, reducing environmental impact while protecting the components during shipping. The company also invests in continuous improvement programs, gathering feedback from the maker community to refine the bracket geometry and material composition for even better performance in future revisions. By offering detailed assembly guides, CAD files for custom enclosure design, and video tutorials, Bolsen empowers users to achieve professional‑grade results without requiring extensive engineering expertise. This holistic approach—combining high‑quality hardware, responsive support, and educational resources—makes the Bolsen ultrasonic sensor mounting bracket a reliable choice for both novice hobbyists and seasoned engineers seeking dependable sensor integration.
