Accurate enough

Using this for obstacle avoidance. Response time is quick enough for slow moving robots.

Good but needs divider

Sensor works well but be careful connecting echo directly to 3.3V boards. Use a voltage divider for safety.

One DOA

Bought a pack of 5, one was dead on arrival. The other four work fine. Customer service was helpful.

5 FAQ

Q: Is there a library available?

A: Yes, many Arduino libraries exist like NewPing.

Q: What happens if object is too close?

A: Readings below 2cm may be unstable or return 0.

Q: Can I use this with Raspberry Pi?

A: Yes, but ensure logic level shifting for the Echo pin.

Q: What is the accuracy?

A: Typically within 3mm under ideal conditions.

Q: Does it work underwater?

A: No, ultrasonic waves do not propagate well from air to water with this module.
