Description
Product Description
The SFM-V1.7 is a premium, small-form-factor fingerprint identification module that utilizes advanced semiconductor capacitive sensing technology. Unlike traditional optical sensors that use a camera and light, the SFM-V1.7 measures the electrical capacitance of a finger’s ridges and valleys. This results in a much higher level of security, as it is nearly impossible to fool with a 2D printed image or a bypass “fake finger.”
This module is an “All-in-One” biometric solution featuring a circular, aesthetic design with an integrated high-speed processor. It handles the entire process of fingerprint entry, image processing, feature extraction, and template matching internally. With its UART (Universal Asynchronous Receiver/Transmitter) communication, it is easily integrated into any microcontroller-based system, offering a sleek, smartphone-like unlocking experience for modern hardware.
Key Features
- Capacitive Sensing Technology: Offers superior anti-spoofing capabilities and higher recognition accuracy compared to optical sensors.
- 360-Degree Recognition: Allows the user to place their finger at any angle; the internal algorithm automatically adjusts for rotation.
- Ultra-Thin & Circular Design: The compact, round form factor is ideal for embedding into door handles, drawer fronts, and handheld mobile devices.
- Self-Learning Algorithm: The module continuously updates the stored fingerprint template with each successful scan to account for minor skin changes over time.
- Intelligent “Wake-up”: Features a low-power sensing pin that alerts the host controller only when a touch is detected, preserving battery life.
- Sleek Visual Feedback: The circular rim is designed to fit seamlessly into high-end consumer electronics and professional office hardware.
