Obstacle avoidance module mounting bracket kit for Arduino Robot car/Smart car (include servos, ultrasonic)

This obstacle avoidance module mounting bracket kit is a complete hardware package designed for Arduino robot cars and smart vehicles. Supplied with servos and an ultrasonic sensor, it provides students, hobbyists and makers with a reliable solution for distance sensing and steering. It is ideal for educational robotics platforms and custom DIY builds.

Robust high-strength acrylic bracket

The mounting bracket is constructed from 4mm thick, high-strength acrylic panels designed to withstand significant impact forces. Its simple yet robust structure provides a stable and durable platform for your robot's obstacle avoidance sensors.

Versatile application areas

This kit is highly suited for a variety of detection tasks, including robot obstacle avoidance, object distance measurement, and level detection. It can also be integrated into public security systems and parking detection setups.

Ultrasonic sensor technical specifications

Operating at DC 5V with a static current of less than 2mA, the sensor provides a high level output of 5V and a low level output of 0V. It features a detection angle of no more than 15 degrees, covering distances from 2cm up to 450cm with an accuracy of 3mm.

Simple wiring interface

The module features straightforward wiring with four main pins: VCC, GND, Trig for the control side, and Echo for the receiving end. This standard interface allows for quick connection to Arduino boards and other microcontrollers.

Basic operating principle

To measure distance, the host controller sends a high-level signal of at least 10 microseconds to the Trig pin, prompting the module to emit eight 40kHz square waves. The Echo pin then outputs a high-level signal corresponding to the time taken for the ultrasonic wave to return, allowing distance calculation using the speed of sound.
