Fast and Reliable
We used ten of these for a university lab locker system. They have been running for three months without any failures. The capacitive sensing works even with slightly dry fingers, which is a plus.

Good value, minor wiring quirks
The sensor works well overall. I had to double-check the voltage levels as it strictly requires 3.3V logic. Once configured correctly, the false rejection rate is very low. Great for prototyping access control systems.

Perfect for student projects
Bought this for our robotics competition entry. It adds a professional touch to our robot's authentication system. The small form factor made it easy to mount inside our chassis.

Excellent for DIY Security Projects
This module integrated perfectly with my ESP32 project. The UART communication is straightforward, and the documentation provided by Hi-Link was sufficient to get it running in under an hour. Recognition speed is impressive.

Works but needs careful calibration
The sensor is sensitive, perhaps too sensitive out of the box. I had to adjust the threshold settings in the firmware to stop it from triggering on noise. Once calibrated, it performs as advertised.

Solid performance for the price
Compared to optical sensors, this capacitive module is much harder to spoof. The SDK examples are basic but functional. I wish there were more Python libraries available, but the C code translates easily.
Q: Can this sensor work through glass or thick plastic?
A: As a capacitive sensor, it requires direct contact with the skin or a very thin protective layer (under 0.5mm). It will not function reliably through thick glass or heavy plastic overlays.
Q: What is the maximum number of fingerprints that can be stored onboard?
A: The module can store up to 150 fingerprint templates internally. If you need more, you would need to manage the database externally on a host MCU or PC.
Q: Does this module support USB direct connection to a PC without a microcontroller?
A: Yes, the HLK-ZW101 supports USB interface mode, allowing direct connection to a PC for enrollment and verification, though driver installation may be required depending on your OS.
Q: Is there a library available for Arduino IDE?
A: While we do not provide an official Arduino library, the module uses standard UART protocols. Many community-developed libraries for similar capacitive sensors are compatible with minor adjustments.
Q: What happens if the power is cut during enrollment?
A: The module has non-volatile memory. If power is lost during an incomplete enrollment process, that specific template slot remains empty, and no corrupted data is saved. You can simply retry the enrollment.
