Product Description

ZW101 / ZW111 Integrated Fingerprint Sensor Module

Low-Power Semiconductor Fingerprint Module for Arduino and Embedded Systems

The ZW101 and ZW111 are lowpower, highperformance semiconductor fingerprint modules from Hi-Link (HLK) . They integrate a fingerprint sensor with a DSP processor into a compact design for biometric security applications.

UltraLow Power Consumption Sleep current as low as 8uA (ZW111) for battery-powered devices.
HighResolution 500DPI Sensor Captures clear fingerprint images with 88x112 pixels for reliable recognition.
Operating voltage is 3.3V DC - ensure a stable power supply .
Connect via serial UART (TTL) - use Arduino's SoftwareSerial or hardware serial pins .
Do not connect the module to 5V directly without level shifting unless specified .

Troubleshooting

Module not responding:

  • Verify 3.3V power supply and stable current (>100mA) .
  • Check UART connections (TX ↔ RX, RX ↔ TX) .
  • Ensure common ground between module and microcontroller .

Enrollment fails with error code 0x26:

  • This indicates poor fingerprint image quality .
  • Clean the sensor surface with a soft cloth .
  • Ensure finger is placed correctly and held steady for the scan .

Automatic registration timing issues:

  • The module needs to be in "waiting" mode before a finger is placed, not before sending the command .
  • Consult the module's protocol specification for the exact command flow .
