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.
