Range varies
It works well for close objects, but I found the 400cm range is optimistic depending on the surface material. Good for the price though.

Good sensor, minor wiring note
Great accuracy within the specified range. Just note that Raspberry Pi users might need a voltage divider for the echo pin. Otherwise, solid module.

Great value
Bought three for a school project. All three worked out of the box. Documentation was clear and easy to follow.

Perfect for robotics
Works flawlessly with my Arduino Uno project. The reverse polarity protection saved me when I wired it backwards initially. Highly recommend for beginners.

Reliable measurement
I've tested this against a more expensive sensor and the readings are consistent. The build quality is sturdy enough for indoor prototypes.
Q: Can I use this outdoors?
A: It is designed for indoor use. Wind and temperature changes may affect accuracy outdoors.
Q: What is the power consumption?
A: The operating current is approximately 15mA during active measurement.
Q: Is this 3.3V logic compatible?
A: The module operates at 5V. For 3.3V systems like Raspberry Pi, a voltage divider is recommended for the Echo pin.
Q: Does it come with a library?
A: No, but it is compatible with standard Arduino Ultrasonic libraries available online.
Q: Can I connect multiple sensors?
A: Yes, you can connect multiple modules using different trigger and echo pins on your microcontroller.
