Product Description

Give your robot a clear view of its surroundings with the Acrylic Mounting Holder for HC-SR04. This lightweight yet durable bracket is specifically laser-cut to fit the standard HC-SR04 ultrasonic sensor module. At Robogears, we recommend this holder for any mobile robotics project to ensure the "eyes" of your robot stay perfectly level and securely attached to the chassis. The transparent design maintains a clean aesthetic for your build while providing rigid support that prevents sensor "jitter" caused by loose wiring. Whether you are building an autonomous maze-solver or a smart parking assistant at your Pimpri workshop, this mounting bracket is the essential mechanical interface for your distance-sensing hardware.

Detailed Key Features

Perfect Fitment: Precisely engineered to snap around the two 16mm transducers (the "eyes") of the HC-SR04 module without obstructing the sonic waves.
Durable Acrylic Construction: Made from shatter-resistant acrylic that can withstand the vibrations and minor bumps typical of hobbyist robotics.
Simplified Assembly: Features pre-drilled base holes, making it easy to screw the bracket onto acrylic, wood, or 3D-printed robot bases.
Protective Film: Comes with a brown paper or clear plastic protective film on both sides to ensure the bracket remains scratch-free until you are ready to assemble it.
Vertical Stability: Holds the sensor at a fixed 90-degree angle to the ground, which is critical for accurate distance calculations and obstacle detection.

All Technical Details

Hole Alignment: The two large holes are spaced exactly to match the center-to-center distance of the HC-SR04 transmitter and receiver.
Base Mounting: Includes two small holes at the base for M3 or M2.5 screws/bolts.
Versatility: While designed for the HC-SR04, it can also fit similar ultrasonic modules like the US-015 or HC-SR05 (verify pin clearance before final mounting).
Applications: Smart cars, automated liquid level monitors, social distancing alarms, and DIY security systems.

Prototyping & Engineering Tips (Robogears Exclusive)

Remove the Film First: At our Pimpri facility, we often see makers forget to peel off the protective brown paper. For a professional, crystal-clear look, peel the film from both sides before installing the sensor.
Avoid Over-tightening: Acrylic is strong but can crack if M3 screws are over-torqued. Use small Nylon Washers if possible to distribute the pressure evenly across the mounting holes.
Servo Integration: For "scanning" behavior, you can easily glue or screw the base of this holder onto a TowerPro SG90 Servo horn. This allows your robot to look left and right to find the best path.
Wiring Clearance: Ensure the pins of the HC-SR04 are pointing upwards or downwards in a way that doesn't put strain on the jumper wires against your robot's chassis.

Package Includes

1 x Acrylic Mounting Holder for HC-SR04 Ultrasonic Sensor (Note: Screws and Ultrasonic Sensor are sold separately unless specified in a kit)

Image Disclaimer

Product images are shown for illustrative purposes only. The thickness or the exact shape of the base "feet" may vary slightly between manufacturing batches, but the compatibility with HC-SR04 sensors and the transparent acrylic material remains as described.
