AS608 optical fingerprint sensor fingerprint module

1. Dimensions (23.3*20.3*48.1)

Overview of the product

The JM-101 fingerprint module is an integrated fingerprint processing module that integrates the light path and the fingerprint processing part. It has the characteristics of small size, low power consumption, and simple interface. High reliability, fast recognition speed, good dry and wet finger adaptability, fingerprint search for fingerprint searchFast speed.

The JM-101 module communication interface is USB and UART communication interfaces.

Three working principles
1. Fingerprint characteristics

The characteristics of the fingerprint algorithm from the obtained fingerprint image represent the fingerprint information.The storage, comparison and search of fingerprints are completed by operating fingerprint characteristics.

2. Fingerprint processing contains two processes: fingerprint login process and fingerprint matching process [The fingerprint matching is divided into two ways: fingerprint comparison (1: 1) and fingerprint search (1: n)].
When login in fingerprints, it is entered twice of each fingerprint and processed the images of 2 entrants to store the synthetic template in the module.
When the fingerprint matching, the fingerprint sensor must be verified and processed by entering the fingerprint image, and then compared with the fingerprint template in the module (if it matches a template specified in the module,Method; if it matches multiple templates, is called fingerprint search method, that is, 1: n method), the module gives the matching results (passed or failed).
