Power Adapter-5V 4A WIKI

Introduction

This is an Arduino compatible fingerprint module. With the high speed DSP processor, it could also work with other serial device, like MSP430, 51, AVR, PIC, STM32, ARM and FPGA device. This fingerprint module could work alone without any principal computer or any PC software. It could store 1000 fingerprint. Support fingerprint entry, intelligent image processing, fingerprint comparison and fingerprint search mode. It also has a high sensitivity to both wet and dry fingerprint recognition. This module could be widely used in security field, such as license management .etc. It can also be used to replace the IC card, password, hardware switch in your application.

Sorry for the inconvenience first, we found this wiki library should be a fork of Adafruit fingerprint's one, the download link will be removed until we fix this wiki

How to use

Input Fingerprint Data

Codes download

Download and install the Fingerprint Library:

Click to download library files Arduino Library Installation Tutorial

Open Fingerprint Library sample code -> fingerprint -> examples -> enroll.ino.
Connect UNO and fingerprint module according to the connection diagram.
If you want to clear all previous saved fingerprint template, please change the number which arrows point 0 to 1, if you don't want to clear all fingerprint data. just keep it "0" in the code.

SEN0188 Fingerprint Sensor with 5 Fingerprint Projects Codes download

Select the Board and Port
Upload
Open Serial monitor

Serial Pont

Set Serial baud rate 9600
No line ending
Check Autoscroll

After you finish seting its parameter and make sure the connection is right, you will get this display in the serial monitor：

Set mode

Set the NL mode to the NL+CR

Enter your fingerprint ID

Now please enter your fingerprint ID in the serial monitor and then click the "Send" button.

Put your finger on the fingerprint module

Don't move finger until you get "Remove finger".

Move your finger

Don't move finger until you see "Remove finger"

Confirm your fingerprint again

It will tell you to enter the fingerprint again, put the same finger on the module again.
Don't move finger until you see "Remove finger"

Store successfully and you can input to the next finger again

Stored successfully
Keep going to input fingerprint if you want

Read fingerprints

Code downloads

Similar to the fingerprint input, download the Exemples -> fingerprint.ino to UNO:
Set Board and Port；
Open Serial Monitor；

Read fingerprints

If the fingerprint module is connect successful, it will always prompt you to press your fingers

Read Succeeded

Press your finger on the screen and do not move, you may also be prompted to press the fingers, but the prompting message will be slower, if your fingerprints has been in the template, it will appear as shown
