Low power consumption as advertised
Battery life on my project has extended significantly since switching to this Hi-Link module. The sleep mode functions exactly as described in the datasheet. Highly recommended for battery-operated devices.

Reliable but needs careful calibration
Good sensor accuracy overall. Had to spend some time tuning the threshold settings for optimal performance in low-light conditions, but once configured, it works flawlessly. Great value for the price point.

Consistent performance
Used these modules for a batch of commercial access panels. False rejection rate is negligible, and users find the scanning process intuitive. Will order more for the next phase.

Good SDK support
The provided library made integration with our STM32 microcontroller very smooth. Only minor issue was a delay in shipping, but the product quality makes up for it.

Compact and robust
The small form factor of the ZW0906 fit perfectly into my tight enclosure design. It feels durable and has withstood several months of daily testing without any failures.

Perfect for custom smart lock projects
Integrated the ZW111 module into a prototype smart lock. The UART communication is straightforward, and the recognition speed is impressive even with dry fingers. Documentation was clear enough to get started quickly.
Q: Can I enroll multiple fingers for the same user ID?
A: Absolutely. The module allows you to store multiple fingerprint templates associated with a single User ID to improve convenience and recognition success rates.
Q: What happens to stored data if power is lost?
A: The fingerprint templates are stored in non-volatile memory within the module. Your data will remain intact even if the power supply is disconnected or interrupted.
Q: Is there a development kit available for this sensor?
A: Yes, we offer a USB-based evaluation kit compatible with all ZW series modules. It includes sample code and a GUI tool for template management. Please check the 'Accessories' section.
Q: What is the maximum cable length for the UART connection?
A: For reliable communication at standard baud rates (e.g., 115200), we recommend keeping the cable length under 30cm. For longer distances, please use shielded cables or signal buffers.
Q: Does this module support wet finger recognition?
A: Yes, the ZW111 series includes algorithms to handle slightly damp fingers, though performance may vary if the finger is excessively wet. We recommend testing in your specific environmental conditions.
