R307 Optical Fingerprint Scanner Module for Arduino

This is R307 Optical Fingerprint Reader Sensor Module. R307 fingerprint module is fingerprint sensor with TTL UART interface for direct connections to microcontroller UART or to PC through MAX232 / USB-Serial adapter. The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person.

The FP module can directly interface with 3.3 or 5v Microcontroller such as NodeMCU and Arduino. A level converter (like MAX232) is required for interfacing with PC serial port.

Integrated image collecting and algorithm chip together, ALL-in-One Fingerprint reader can conduct secondary development, can be embedded into a variety of end products. Users can conduct secondary development, can be embedded into a variety of end products, such as access control, attendance, safety deposit box, car door locks

Low power consumption, low cost, small size, excellent performance, Professional optical technology, precise module manufacturing techniques. Good image processing capabilities can successfully capture an image up to resolution 500 dpi Finger detection function.

Features:

• Perfect function: independent fingerprint collection, fingerprint registration, fingerprint comparison (1: 1) and fingerprint search (1: N) function.
• Small size: small size, no external DSP chip algorithm, has been integrated, easy to install, less fault.
• Ultra-low power consumption: low power consumption of the product as a whole, suitable for low-power requirements of the occasion.
• Anti-static ability: a strong anti-static ability, anti-static index reached 15KV above.
• Application development is simple: developers can provide control instructions, self-fingerprint application product development, without the need for professional knowledge of fingerprinting.
• Adjustable security level: suitable for different applications, security levels can be set by the user to adjust.
• Finger touch sensing signal output, low effective, sensing circuit standby current is very low, less than 5uA.
