R307 Optical Fingerprint Sensor Module

The R307 Optical Fingerprint Reader makes fingerprint scanning straightforward. It connects easily to microcontrollers or PCs using a TTL UART interface or through a MAX232/USB-Serial adapter. You can store fingerprints on the device and set it to recognize individuals in different ways.

This fingerprint sensor module includes an optical sensor, a fast processor, and smart algorithms for capturing and matching fingerprints. It works with 3.3V or 5V microcontrollers and is great for projects like access control systems, attendance tracking, or secure locks. It’s small, uses little power, and captures clear fingerprint images with a resolution of up to 500 dpi.

1. How does R307 work? 

  • The R307 fingerprint module has a TTL UART interface for direct connection to a microcontroller UART or a PC via a 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. 

2. Where is the fingerprint sensor module commonly used? 

  • The fingerprint sensor module is used as a way to verify identity. It is widely applied to computers, mobile phones, electronic door locks, access control systems, security safes, etc. 

3. What is the output of fingerprint scanner? 

  • The output of fingerprint sensors is a 2D gray-scale image of a fingerprint, which is then ready for analysis. The image is stored locally, preferably in a secure area of the phone, and in an encrypted form 

4. Which interface does the R307 Optical Fingerprint Reader Sensor Module use?

  • The R307 Optical Fingerprint Reader Sensor Module is a fingerprint sensor with a 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.
