R503 Fingerprint Sensor is a device that allows you to read and save up to 200 fingerprints through a touch panel, it also contains a configurable LED light indicator. This sensor is small and easy to use, it has a wide detection range, a nut so you can install it easily and it has 6 pins, 2 for power, 1 for the finger detection signal, another for the touch power and 2 for communication via serial protocol (Tx, Rx) so you can use it with Arduino, ESP32, PIC and other microcontroller development boards.

R503 Fingerprint Sensor can be used in security, access control and attendance applications, you can use the LED colors to indicate errors in the census, fingerprints found in the records, fingerprints not registered, among other things.

Feature:

• With its built-in algorithm chip and circular acquisition chip, using a 192x192 pixel sensor, it can store 200 fingerprints.
• With integrated image collection and an algorithm chip, it has professional performance.
• High recognition rate and is flexible for use; it can adapt to dry fingers, wet fingers, light-textured fingerprints, and old fingers.
• Wide application areas can be embedded in a variety of final products, such as access control, assistance, and safety boxes.
• Simple installation; no need for complicated tools; convenient for using
