Excellent documentation included
Unlike other sellers, this package actually includes clear PDF guides and example code. It made integrating the HY-SRF05 into my final year project much easier. Highly recommended for students.

Perfect for robotics projects
This sensor works flawlessly with my Arduino Uno. The range is accurate up to about 3 meters in my testing, and the documentation provided was very helpful for getting started quickly.

Good value, slight noise at max range
Great little module for the price. It performs well within the 2cm to 300cm range. I noticed some fluctuation when measuring objects near the 400cm limit, but for most hobby applications, it is more than sufficient.

Reliable and consistent
I bought ten of these for a workshop. All units performed consistently right out of the box. The 5-pin layout is standard and easy to wire up on a breadboard.

Easy to use for beginners
As someone new to electronics, I found this sensor very forgiving. The trigger and echo pins are clearly labeled, and the online community support for this specific model is huge.

Works well for obstacle avoidance
Using this on a custom drone build for low-altitude obstacle detection. Response time is fast enough for slow-moving robots. Just ensure you have a stable 5V power supply.
Q: What is the beam angle of the ultrasonic waves?
A: The measuring angle is approximately 15 degrees. This means it detects objects within a cone shape extending from the sensor face.
Q: Can this sensor work underwater?
A: No, this module is not waterproof and is designed for air-based ranging only. Ultrasonic waves also behave differently in water, requiring specialized transducers.
Q: Does the included documentation have code examples for Raspberry Pi?
A: The primary documentation focuses on Arduino C++ examples. However, the timing principles are the same, and many users have successfully adapted it for Python on Raspberry Pi using GPIO libraries.
Q: How do I handle the 'OUT' pin on the 5-pin configuration?
A: On many HY-SRF05 variants, the 5th pin (OUT) is an optional overflow indicator that goes high if the distance exceeds the measurable range. It can often be left unconnected for basic usage.
Q: Is this compatible with 3.3V logic microcontrollers like the ESP32?
A: Yes, but you may need a voltage divider or level shifter for the Echo pin output, as the sensor operates at 5V. The Trig pin can usually be driven directly by 3.3V logic.
