Fingerprint Recognition Module ZW111 Integrated Fingerprint Sensor Low Power Finger Detection Capacitive Semiconductor
ZW111 is an all-in-one semiconductor fingerprint processing module, which consists of an active semiconductor fingerprint capture SENSOR and a fingerprint identification processing chip.
Fingerprint identification algorithm chip adopts high-performance, low-power Riscv core, running 360-degree adaptive self-learning algorithm.
Semiconductor Sensor adopts active RF acquisition, supports low-power finger detection, eliminates the need for external finger touch detection chip, high integration, simple product structure, and improves the stability and consistency of the product.
At the same time to provide seven-colour light effect, can be customized according to user requirements of different colors and display mode.
Application
access control systems
attendance settings
banking and financial identity authentication
electronic signatures
etc.

Specifications/features

To reduce the power consumption of the fingerprint module by controlling the power supply of the fingerprint module VCC or not, the circuit is shown in the following figure:
VIN is the client 3.3V voltage,
VCC is the fingerprint module VCC, and
CTRL is the client MCU I/O control signal;
CTRL is the client MCU I/O control signal;
CTRL controls the fingerprint module VCC on and off.
