Capacitive Fingerprint Sensor Arduino Tutorial || R502/R503 Fast & Best Fingerprint Scanner

Register and get $100 from NextPCB: PCB Assembly capabilities info: ??????? ???????????: In earlier videos, I discussed optical fingerprint sensors like R305 and R307. I recently made a tutorial using GT511C3 Optical Fingerprint Sensor. But capacitive fingerprint sensors are much better and more advanced. Actually, there are 3 different types of fingerprint sensors available in the market. They are optical, capacitive, and ultrasonic. All of them works using different algorithm and image recognition system. Anyway our main focus today will be only on R502/R503 Capacitive Fingerprint sensor. We will learn how capacitive fingerprint sensing technology works in detail. Then we will learn about the construction design and pinout of the R502 Fingerprint sensor. We will then interface R502/R503 Capacitive Fingerprint Scanner with Arduino. Then taking the Adafruit Fingerprint Sensor library, we will enroll the fingerprint and then later read the stored fingerprints stored in the database. ....................................................................................................................................................................................................................................
