Description

The Acrylic Fixed Bracket is a dedicated mechanical accessory designed to securely house the HC-SR04 ultrasonic sensor module. Its precise cutouts and mounting holes ensure the sensor’s transmitter and receiver elements are held in a fixed, parallel orientation, which is critical for maintaining the sensor’s specified 2cm to 400cm measurement accuracy and 40kHz operational frequency.

Constructed from durable acrylic, the bracket provides a rigid platform that minimizes external vibrations and positional drift, common issues in mobile robotics or vibrating machinery. This stability directly enhances the reliability of the echo timing measurements used for distance calculation. The included screw set allows for quick mounting to various surfaces, streamlining integration into prototypes, educational kits, or final automated systems.

Key Features

  • Precision-Fit Design: CNC-cut acrylic bracket with exact tolerances for the HC-SR04 module, ensuring optimal sensor positioning.
  • Vibration-Damping Structure: Rigid acrylic construction absorbs minor shocks and vibrations to prevent measurement noise.
  • Complete Hardware Kit: Includes all necessary screws for securing both the sensor to the bracket and the bracket to your project chassis.
  • Lightweight & Low-Profile: Minimal added weight and compact dimensions (50x30x20mm) preserve system agility and design flexibility.
  • Enhanced Measurement Integrity: By fixing the sensor alignment, it prevents angle-induced errors, ensuring consistent performance across the full 2-400cm range.
  • Broad Compatibility: Designed for the standard HC-SR04 pinout and form factor, compatible with all derivative modules and common 5V logic systems.

Applications

  • Mobile robot obstacle avoidance and navigation systems
  • Automated inventory level sensing and bin filling detection
  • DIY parking sensor and proximity warning assemblies
  • Educational robotics and STEM kit sensor mounting
  • Precise positioning jigs for manufacturing or 3D printer bed leveling

Frequently Asked Questions

Is this bracket compatible with the HC-SR04P (3.3V) version of the sensor?

Yes, the bracket is mechanically compatible with both the standard 5V HC-SR04 and the 3.3V logic HC-SR04P modules, as they share the same physical footprint and mounting hole positions. The bracket only provides physical mounting support and does not affect the electrical operation.

What screws are included, and what do I need to install it?

The included screw set typically contains M2 or M2.5 screws of appropriate length to first secure the HC-SR04 module to the acrylic bracket, and then to mount the assembled bracket onto your project's surface (e.g., a robot chassis or panel). No additional tools are required beyond a standard Phillips-head screwdriver.

How does using a bracket improve the HC-SR04's performance?

The primary benefit is stability. By fixing the sensor in a rigid, predefined orientation, the bracket eliminates tilt and vibration that can cause inconsistent echo reception and measurement errors. This is especially critical in moving platforms like robots, where it ensures the sensor's 40kHz ultrasonic beam points consistently in the intended direction for reliable 2-400cm distance readings.
