Working Principle
The HLK-FPM383F uses capacitive sensing technology to detect the unique ridge and valley patterns of a fingerprint.
When a finger is placed on the sensor, the module captures the fingerprint pattern and processes the biometric information internally. The fingerprint can then be enrolled into the module’s internal memory or compared with previously stored fingerprint records for authentication.
The module communicates with the host controller through its UART interface. A compatible microcontroller can send commands to perform supported fingerprint functions such as enrollment, verification, identification, and user management.
Low-Power Operation
The module is designed for applications where power consumption is important. During normal operation, the module consumes up to approximately 40mA, while its sleep mode can reduce consumption to a maximum of approximately 25µA.
This makes the sensor suitable for battery-powered devices that remain in standby for long periods and only activate the fingerprint sensor when user interaction is detected or authentication is required.
ESD Protection
The HLK-FPM383F includes ±15kV static protection, helping improve the module’s resistance to electrostatic discharge during normal handling and operation.
This makes it suitable for embedded products such as locks, access-control devices, portable electronics, and other user-facing systems where the sensor may be touched frequently.
Communication Interface
The module uses a UART communication interface for connection with a compatible microcontroller or embedded controller.
The specified default communication speed is 57600 bps. The 6-pin, 1.0mm-pitch connector is located on the rear side of the module.
Users should refer to the supplied datasheet and pinout information before connecting the module to a microcontroller.
