Perfect for my smart home project
This sensor works flawlessly with my Arduino setup. The I2C communication is stable, and it recognized all 9 gestures accurately within the specified range. Highly recommended for DIY automation.

Great documentation support
Found plenty of example code online which made getting started very easy. The sensor is small enough to fit into tight enclosures without issues.

Excellent gesture recognition
I used this for a robot arm controller. The response time is incredibly fast, and false positives are rare. The build quality of the module feels solid.

Solid performance for the price
Works well for basic gesture inputs like swipe left/right and up/down. Not suitable for complex motion tracking, but exactly what was needed for my menu navigation system.

Reliable and compact
Been running this in a prototype for two weeks without any glitches. The low power consumption is a bonus for battery-operated devices. Will buy more.

Good value, easy to integrate
Integration was straightforward using existing libraries. The detection range is decent for close-proximity controls. Only minor issue is sensitivity to bright ambient light, but manageable.
Q: Is this compatible with 5V Arduino boards?
A: Yes, the module supports an operating voltage range of 3.3V to 5V, making it fully compatible with standard 5V Arduino boards like the Uno and Mega.
Q: What is the maximum detection distance?
A: The optimal detection range is between 0 and 15 cm. Performance may degrade beyond 15 cm depending on lighting conditions and the speed of the gesture.
Q: Does it come with a library for Raspberry Pi?
A: While we do not provide an official Python library specifically branded by us, there are several open-source Python libraries available on GitHub that work perfectly with this module on Raspberry Pi.
Q: What are the 9 specific gestures recognized?
A: The sensor recognizes: Right, Left, Up, Down, Forward, Backward, Clockwise, Counter-Clockwise, and Wave.
Q: Can multiple sensors be used on the same I2C bus?
A: No, this specific module has a fixed I2C address. To use multiple sensors, you would need an I2C multiplexer.
