AS608 Optical Fingerprint Sensor Pinout

This Module has 4 useful pins: ► V+: Module power supply – 3.3V ► GND: Ground ► TX: Serial Transmitter ► RX: Serial Receiver

Interfacing AS608 Optical Fingerprint Sensor with Arduino

The following circuit show how you should connect Arduino to AS608 sensor. Connect wires accordingly.

Step 2: Library

Step 3: Enrolling Fingerprint

The below program is for enrolling fingerprints. With this program you can enroll 127 different fingerprints. Run the program and open the Serial Monitor.

The general process for enrolling a fingerprint is as follows:

1- Enter Fingerprint ID 2- Place finger on sensor 3- Place finger on the sensor again

1- Enter Fingerprint ID

Before enrolling any fingerprint, you must first enter its ID. You are allowed to choose the number 1 to 127. For example, in the image below, we have selected number 3.

2- Place finger on sensor

3- Place finger on the sensor again

Now you have to put your finger on the sensor again for the second image. When this step is completed correctly, the phrase Stored will appear.

Step 4: Test and Verify fingerprint

First, upload the following code to Arduino.

This code is for testing and matching fingerprints. First run the program and then open the Serial Monitor. At this point, the program waits for a finger to be placed on the sensor for identification. After placing the finger on the sensor, the phrase “Match” is displayed if the fingerprint is already stored, and phrase “Not Match” is displayed if fingerprint is not detected. In addition, if fingerprint is identified, the corresponding ID will be specified.
