## Long description

The SPC HC-SR04 ultrasonic sensor SEN-US01 distance measuring module is a reliable component designed for various microcontroller and electronics projects. Utilizing sonar technology, it provides accurate non-contact distance measurements, making it a practical choice for makers, hobbyists, and engineers working on prototyping and automation systems.
Advantages
This ultrasonic sensor delivers precise distance detection without physical contact with the measured object. It integrates easily with popular microcontroller platforms, ensuring straightforward setup for electronic prototyping. The module offers a cost-effective solution for adding spatial awareness to DIY hardware builds and educational engineering projects.
Suitable for
Obstacle detection in mobile robotics
Distance measurement and monitoring projects
Basic automation and proximity sensing systems
Educational electronics and microcontroller experiments
When it may not be suitable
This module is not intended for high-precision industrial measurement tasks or long-range outdoor detection where environmental conditions like wind, heavy rain, or extreme temperatures can interfere with ultrasonic waves. It may also struggle to accurately detect soft, sound-absorbing surfaces or objects positioned at a very sharp angle relative to the sensor.
Key specifications
Non-contact ultrasonic distance measuring technology
Compatible with standard microcontrollers
Designed for electronics and robotics projects
How to use
To use the sensor, connect the trigger and echo pins to the digital I/O pins of your microcontroller, along with the appropriate power and ground connections. Send a short trigger pulse to initiate a measurement, and measure the duration of the echo pulse to calculate the distance to the target object based on the speed of sound.
What to consider before purchase
Verify the operating voltage compatibility with your specific microcontroller board
Consider the measurement range and beam angle limitations for your application
Ensure your project environment is suitable for ultrasonic wave propagation
For optimal performance, mount the sensor securely to avoid vibration interference and ensure there are no obstacles directly in front of the transducers during operation.
