The Mounting Bracket for Ultrasonic Sensor HC-SR04 is a lightweight and durable holder designed specifically for securely mounting the HC-SR04 ultrasonic distance sensor module in robotics, automation, and electronic projects. The bracket provides stable sensor positioning and helps maintain proper alignment of the ultrasonic transmitter and receiver for reliable obstacle detection and distance measurement applications.
The bracket is commonly manufactured from acrylic material and features two circular openings that align with the ultrasonic transmitter and receiver of the HC-SR04 sensor. Its precision-cut construction allows the sensor module to fit securely while keeping the sensing elements unobstructed. Common acrylic versions have a thickness of approximately 2.8–3mm, sensor openings around 16mm, and mounting holes around 3.4mm, although dimensions vary by bracket design.
The mounting bracket can be installed on robot chassis, smart cars, servo motor assemblies, pan-and-tilt mechanisms, and fixed structures. It is especially useful in obstacle avoidance robots where the sensor must remain securely positioned and correctly oriented during vehicle movement.
Its compact size, simple installation, and compatibility with the standard HC-SR04 sensor make it suitable for Arduino robots, Raspberry Pi projects, ESP32-based automation systems, autonomous vehicles, parking sensors, and educational STEM projects.
