Good Value
Solid sensor for the price. Note that it needs 5V logic, not 3.3V directly.

Great for Arduino Projects
Works perfectly with my Arduino Uno. Easy to wire and plenty of libraries available.
5 FAQ
Q: What is the maximum angle for detection?
A: The measuring angle is typically less than 15 degrees for optimal accuracy.
Q: Does it work underwater?
A: No, this is an air-based ultrasonic sensor and is not waterproof or designed for underwater use.
Q: Is there a library for ESP32?
A: Yes, there are multiple open-source libraries compatible with ESP32 available on GitHub.
Q: Can I use multiple sensors together?
A: Yes, you can use multiple sensors by triggering them sequentially to avoid interference.
Q: Can this work with 3.3V logic?
A: While the sensor operates at 5V, logic levels should be checked. We recommend a level shifter for 3.3V boards.
