The HC-SR04 Ultrasonic Range Finder is a widely used sensor designed for measuring distances and detecting objects. This module features two front-facing components, serving as an ultrasonic transmitter and receiver. It operates using sonar technology, similar to how bats and dolphins detect objects.
This sensor combines a transmitter, receiver, and control circuit in one compact module. It offers excellent range accuracy and stable readings, making it easy to use in various applications. Unlike some rangefinders, the HC-SR04 is unaffected by sunlight or dark materials, although soft acoustic materials like cloth may be harder to detect.
The Trigger and Echo pins serve as the module’s I/O pins, allowing connection to a microcontroller or Arduino. When the receiver detects the returning sound wave, the Echo pin goes high for a duration corresponding to the time it took for the wave to return.
The HC-SR04 Ultrasonic Module provides non-contact distance sensing with a range of 2cm to 400cm and an accuracy of up to 3mm. This package includes the HC-SR04 sensor and an acrylic mounting bracket for easy installation and assembly.

Frequently Asked Questions
What distance range can this sensor reliably measure?
This HC-SR04 module accurately measures distances from 2 cm up to 400 cm in typical use, with a maximum echo detection capability of around 4500 cm under ideal conditions.
Will it work outdoors in bright sunlight?
Yes, the HC-SR04 uses ultrasonic pulses, so ambient light doesn’t affect its performance. However, extremely soft surfaces like fabric may absorb sound and reduce accuracy.
How do I secure the sensor using the cartoon bracket?
The acrylic bracket has 3.8 mm diameter holes matching the sensor’s mounting posts. Attach the sensor with small screws or nylon spacers (not included) to hold it firmly in place and maintain correct alignment.
