AJMRTC HK-ZW3020 Capacitive Fingerprint Sensor Module, Touch Finger Detection Semiconductor Fingerprint Identification Unit, TTL Serial Communication for Access Control Lock DIY Project, Single Module

AJMRTC HK-ZW3020 fingerprint identification module adopts capacitive semiconductor sensing technology. It supports touch detection, which can wake the sensor automatically when a finger approaches. It communicates with the main controller via standard TTL serial port, and provides complete fingerprint functions including registering fingerprints, matching verification, deleting fingerprint data and reading fingerprint ID. The built-in algorithm delivers fast matching speed and good anti-dry finger and anti-static interference capability. It works well under normal indoor environments. You only need to send corresponding serial instructions to complete identity recognition logic development. Widely used for electronic smart locks, access control systems, safe cabinets, student electronic projects and embedded identity authentication equipment.
