Accurate and Reliable
Using this for obstacle avoidance on a robot car. Very responsive and accurate enough for the task.

Good sensor, slight learning curve
The 5-pin setup took me a moment to figure out compared to the standard 4-pin version, but it works well.

Works but docs are thin
The sensor functions correctly but the included documentation was a bit vague on timing diagrams.

Perfect for Arduino Projects
Works flawlessly with my Uno. The range is consistent and easy to calibrate.
5 FAQ
Q: Is this compatible with 3.3V logic boards?
A: While powered by 5V, the echo pin may need a voltage divider for safe 3.3V board interface.
Q: Can it detect transparent objects like glass?
A: Ultrasonic sensors often struggle with soft or angled surfaces like glass due to sound wave absorption.
Q: What library should I use for programming?
A: The standard NewPing library supports this module generally without modification.
Q: Does it work reliably outdoors?
A: It can be affected by wind and ambient noise, so it is best suited for indoor use.
Q: How is this different from the HC-SR04?
A: The HY-SRF05 often includes a 5th pin for additional output functionality compared to the 4-pin SR04.
