Perfect for my robotics project
The RGB LED feature makes debugging so much easier. The distance readings are consistent and the included code examples got my robot car moving in minutes.

Solid performance
Good detection range up to 4 meters. The documentation could be slightly more detailed for advanced users, but the basic examples work flawlessly.

Great value for the price
Works exactly as described. The luminous effect is a nice touch. Only minor issue was that the pins were slightly bent upon arrival, but easy to fix.

Kids love the light show
Bought this for a school science fair project. The sensor is accurate and the changing colors keep the kids engaged while learning about ultrasonic waves.

Reliable and easy to integrate
I have used standard HC-SR04 modules before, but the added visual feedback on this Huaner module is a game changer for troubleshooting logic errors.
Q: Does this module work with 3.3V logic levels?
A: While the module operates at 5V, the echo pin can often be read by 3.3V microcontrollers, but we recommend using a voltage divider for safety to protect your board.
Q: Can I control the RGB color patterns via code?
A: Yes, the RGB LEDs are programmable. The included examples show how to change colors based on the detected distance thresholds.
Q: Does the package include jumper wires?
A: The package includes the sensor module and a link to digital resources. Jumper wires are sold separately to allow you to choose the length you need.
Q: What is the refresh rate of the sensor?
A: We recommend a measurement cycle of at least 60ms to ensure accurate readings and prevent signal interference between pings.
Q: Is the mounting hole size standard?
A: Yes, the mounting holes are spaced to be compatible with standard servo mounts and common robot chassis frames.
