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.

Magnificent , I had this sensor for a long time and tried several codes and libraries and none of them worked, you Sir, made it work, thank you so much. I was about to throw it away as I thought I killed it with 5V serial connection but it does work, just connect the red wire to the 3.3V output of the Arduino UNO and the green and white wires to pin D2 and D3, mine were reversed btw. Now I can make a custom board and use this little marvel. Thank you so much 🙂

Its very nice to know that finally you made it work.
What is the code for led blink in r503 ???
Is there a possibility to copy fingerprint data ober to a 2nd r503 scanner?
sir can i store fingerprints in any server ? so that i can access that data from any of the connected module ? and can i store more than 200 fingerprints if it is stored anywhere else?
Hi!!! I am interested in this project. I just had a question. Can we use this sensor to unlock our pc as well??
Hey, I bout the SFM-V1.7 capacitive fingerprint sensor, but I don't seem to find any documentations on it, like it's arduino codes, can you help please?
Sir is there any module available for virtual implementation in proteus ?
Great video, thanks! Q: Adafruit library is meant for optical fingerprint sensor I assume, and this is a capacitive Fingerprint Sensor. Does not capacitive fingerprint sensors use a different algorithm than optical?
Hello sirr...can you please share the link of fingerprint sensor R502/R503
Why are there two separate power wires for the device and the touch sensor? (red and white wires)
Thanks for your great video, but mine didn't work at all. Sensor isn't recognized while I did everything as explained in the video. Anyone else having same issue? I use R503 sensor.
Awesome video and great explanation sir 🔥
Can I have a product to display company logo on screen when I puth my fingerprint ?
How did you connect the Red and White wire into 1 wire?

Great explanation
How do i add bluetooth with finger sensor(is it possible)?.
Excellent
Is the fingerprint stored on the sensor chip or the Arduino?
