Biometric attendance system using fingerprint scanner and NodeMCU with a database & 3D printed case
Вставка
- Опубліковано 4 жов 2024
- Hi everyone.
As we know any attendance system must be secured whether it uses RFID cards or fingerprints or something else.
So as you've already known the RFID based attendance system uses tags, which can be exchanged between users, while the biometric attendance system uses organic matter that cannot be exchanged and that's a good thing.
Recently, I made two videos on using RFID as an attendance system, and many guys asked me to make it using the fingerprint scanner.
Therefore in this video, I'm going to show you how to make a full attendance system using fingerprint scanner and NodeMCU, Also there a website and database to store the users' data and their logs.
**************************************************
The instructions that you need:
1_ The parts:
1* NodeMCU
2* Fingerprint scanner
3* OLED display 0.96in
2_ Install the ESP boards on the Arduino IDE using the additional links:
arduino.esp8266...
dl.espressif.c...
3_ Include the Adafruit libraries:
github.com/ada...
github.com/ada...
github.com/ada...
4_ Download the NodeMCU_Fingerprint code.
5_ Put your WiFi credentials( SSID, Password) with your computer IP or your Server domain in case you're using a public one.
6_ Install a local server like xampp server or wampserver:
Xampp:
www.apachefrie...
Wamp server:
www.wampserver....
7_ copy the biometric attendance folder into xampp/htdocs folder or into wamp/www folder.
8_ go to localhost/biometricattendance/install.php in order to install the database.
9_ then go to localhost/biometricattendance/index.php to start.
Actually, the full process is a bit complicated and I couldn't explain everything in the video.
**************************************************
Note: These codes for the old version:
I will upgrade the code from time to time so consider checking it on my GitHub repository, this code version is 1.2
Download The diagram, the NodeMCU code, the 3D module and The website files from here:
github.com/Inf...
In case you want to use ESP32 then use this code:
github.com/Inf...
The Fingerprint scanner is connected to Tx2 & Rx2
The OLED display is connected to (22 SCL, 21 SDA)
**************************************************
Note: The new version of the website, NodeMCU code and ESP32:

Thanks a lot for your great project. I have put some issues in your github project like new functionallity yo your project. May be all of us could improve the code in github. May be you could check what I have ask you. Thanks a lot. (NOTE: what software do you use to create or modify the 3D case?)
Glad you liked it.
That's will be awesome, thanks, Let me know what you want me to do.
Yes, I did.
The 3D software is FreeCAD, I've mentioned it in the video description.
@@ElectronicsTechHaIs i have created two issues in github. Do you see them?
Yes, I did.
Hello sir! I copied the program and threw it into the arduino.I downloaded the necessary libraries from your site.
Then I chose NodeMCU 1.0 (ESP-12E Module).When I say compile.NodeMCU 1.0 (ESP-12E Module) returns an assembly error.
Why do you think he did it? Help me please...
I don't believing that Wow. this project is working perfectly now. I don't know how to thank you man, you're the best.
Thank you very much, you made my day.
Glad you liked it and you found it helpful.
My pleasure. I'm trying to give the good knowledge for everyone.
Thanks man idk how to thank you for providing this open source, your awesome
My pleasure,
Glad you liked it.
Sir i need your help , please tell me how I can change the colors and all of the website, some changes like title and all are reflecting which are in php files. But css files are not editable. Please help me out.
Cant wait for your next video and I did this project but I had a lot of problems on the way that took time to solve them. Finally I have a working fingerprint Attendance System. Thank you electronics tech. Waiting for you to hit 1K!!!
Good to hear that, I know this project is a bit difficult to create and there no information about it that on the internet so that's why I made it.
What do you suggest for the next video? I made many projects with Ethernet, Blynk with a web interface, NRF24L01 with Blynk and RFID and other project
I was trying last few days to run the code on WAMP Server and few of my web servers, but unfortunately it does not work. On XAMPP server installed on a local computer it works like a charm. But this awesome project should work on every server! So far I understand, it is failing to work due to some restrictions in MySQL on WAMP and other web servers. Last week you uploaded the modified the getdata.php but that did not solve the problem. I sincerely believe that a little more attention from you will solve the problem and make the project really useful.
Adding 'Wifi Manager' would make it even more useful.
Once again my heartfelt thank to you for this nice project
Hi, thanks for the useful feedback.
Before I uploaded this project, I've tested it on many servers like wamp, xampp, 000webhost, infinityfree and 2host many times and it worked as intended.
So when you used wampserver, you were able to access the website from your mobile browser?
Can we use fingerprint scanner as608
You never fail to amaze me sir. Biggest fan here!
Glad you like it. You're welcome whenever you want my friend.
Hello Sir
Did not find fingerprint module...
Please help me 😭😭😭
Tqs for your brief explanations ,sir 😍
Hello sir, nice video with great explanation!
I'm stuck at the oled image of finger with image lock beside, and I've tried downgrading the version to 2.4.2 and also 2.4.1. But sadly, the problem has not been solved.
Please advise!
Hi, Which model do you have?
Did you check the fingerprint scanner baud rate?
Remove all the ESP8266 libraries that you have tried then install just 2.4.2 version.
@@ElectronicsTechHaIs hello sir, i already try your suggestion but the problem has not been solved. I'm used AS608 Fingerprint modul.
Sir really appreciate your work
God bless you
may I know is this project suitable with 5-volt fingerprint sensor because i tried to connect fingerprint sensor but it said the fingerprint sensor not detected :((
Yes, Just connect the scanner Vcc to Vin of the NodeMCU not to 3.3v, and it should work.
Same here, I can't get my fingerprint sensor to read, it lights up but the Serial Monitor tells me that the fingerprint sensor cannot be found. I connected it to the Vin but it still tells me that the sensor can't be found.
I'm using a genuine adafruit DY50 fingerprint module too.
Guys, DY50 module needs 3.3v not 5v, please check the sensor datasheet before using it.
The ESP8266 library version should be 2.4.2 or 2.4.1 so downgrade it if you have a newer version.
@@ElectronicsTechHaIs sir i tried everything but it still not working to detect my fingerprint sensor
Try the fingerprint scanner examples to test it.
The code works with no problem, When I made it and I tested it for many times before I uploaded the video. If there a bug in the website let me know.
Thank once again.In last comment "Is it possible to incorporate more fingerprint attendance system unit using one DB.Different ID provide for each unit."
1,What is the change in some modifications in data_get.php
2.IN NodeMCU_Fingerprint code what to change.
Thank you once again for your efforts to help me.
My pleasure.
yes, you can do that.
you need to add an ID for each scanner then modify the data_get.php file to manage the IDs, also you should add the ID into the database so each entry will be set to the correct scanner.
you are such a genius
Thanks my friend, Glad you liked it.
great all works fine!!!
hi can u pls send me the file and code of the arduino ？
Best UA-cam channel thank you so much :)
Thank you for the feedback.
I'm glad you liked my videos.
Do u have any idea to store more than 128 fingerprints ?
I would have greatly appreciated if you would had described the fingerprint sensor library functions how do they work and about parameters they work with. However, like most of the youtubers were knowingly didn't exposed that information to us so.
I've added comments next of each line to explain the code as possible, If you have an question regarding the code you can email me and I will explain it to you, No problem.
Thanks a lot for the Biometric attendance system using fingerprint scanner and NodeMcu with a database. Awesome project. I have compiled the whole project as you have mentioned works perfectly, except that the blue led keeps blinking randomly. So the users will not be able to register. It is not keeping the led light stable. Please help
Glad you liked it.
Check the wiring and scanner voltage it might be low for your scanner.
Hello sir,the video was very helpful!However,when i open the userslog,the oled scanned my fingerprint and it say welcome but my page didnt load anything.Ive check my database and the data was inserted too,but only timein was inserted.If i want to try again,new row added but my timeout remaining blank.what should i do?thank you.
Hello, the explanation was awesome.
I am getting a fingerprint with lock symbol on the oled display.can you help me?
Make sure that the scanner is connected properly to the esp.
Did you fix this problem?
After uploading, I am getting a fingerprint with lock symbol on the OLED display. While the R307 fingerprint sensor only blink once and then it stopped. What do I need to do?

Hi! What battery are you using? Would you have the battery specs to tell me?
Hi, it's the 18650 Li-ion battery.
Thanks!

Hello sir, i"m using NodeMCU v3. Why i can't add any fingerprint and the ssd1306 can't display anything. I've followed all the step and repeat it many times. thanks
hello sir excellent work i loved it, i have just one request i hope u can help me please can you show us how to store the fingerprint itself in the sql database in order to receive like 1000 student per year and in this case you will pass the limit of the fingerprint reader and this will make your project literally perfect because i googled a lot and there is no one who did it with this set up so you gonna be the 1st in the world so please can you help me ?
Hi, thanks, glad you like it.
that will make the process a bit slower, also that depends on the type of the fingerprint scanner itself like this one that I've used, it doesn't have the feature to get the fingerprint image out of it. but there are some modules that have this feature and they support more than 1000 fingerprints.
Anyway, I will consider that and I will publish my results in the future, thanks.
thanks sir you are great
@Electronics Tech I am using this on my google cloud server for the remote fingerprint authentication testing, earlier I used it on my Linux server hosting which was giving an error of "You cant add more than one fingerprint at time", so I guessed it might because of Cloudflare, now it's not showing that error, now OLED is not showing scanning and sensor is not lighting up at all. It runs perfectly on my XAMPP local server. But the remote thing is not working. I double-checked the databases are working perfectly as I am basically running XAMPP on Google Cloud but still it's stuck there. Please help.
Hi,
"You cant add more than one fingerprint at time" this is not an error message, it's to show you that you have to scan your fingerprint then add a new fingerprint.
I've updated the project codes please consider testing them:
github.com/InfinityWorldHI/Attendance-system
@@ElectronicsTechHaIs Sir the link provided is not working please check and give new link
Hello! The project seems great! Thank you for sharing! I was trying to pull something like this off but I need the fingerprint to be stored in a centralised system and the fingerprint module just read the fingerprint and forward the data to the system and then get a feedback. The fingerprint template should not be there in a module. Can we do that?
Hi, my pleasure.
You're right the fingerprint module stored the images into its memory with ID for each fingerprint then it will send that ID to the server to save it so the fingerprint IDs are stored into the module as well as into the database.
So to store the images outside of the scanner that depends on the fingerprint module that you will use.
No finger in the fingerprint sensor but error is delete the finger from the scanner? Please reply soon as possible
Hi, its me again.
There's one posibility to joint this and the rfid project together?
As if we were looking for more security.
Thank you again for this projects.
Hello,
Yes, you can combine both of the RFID and the fingerprint into one device.
I'm glad it was useful.

Will my project stop recording attendance?
Glad you like it.
Yes, it will.
So amazing We thank you

I have to shift this project to another laptop but how can i delete stored fingerprint or reset the whole project please help
Upload the included example in fingerprint library examples called empty database, then follow the instruction that appeared in the serial monitor.
You are an amazing man
Thanks, my friend.
Thanks a lot for your great project. If possible pleas make this project using SIM800L where WiFi not available.
Glad you liked it,
Actually, I've made it with SIM800L, I will try to publish the video soon.
Sorry for the late reply.Your link may help me more.
Is it possible to incorporate more fingerprint attendance system unit using one DB.
Different ID provide for each unit.
Thank you once again for your efforts to help me.
Yes you can,
You need to add an unique ID for each scanner in order to let the website know the incoming data source.
You can do that by adding the ID in the http request(POST).
Then you should make some modifications in data_get.php to achieve your needs.
Good day sir, I got a question: What voltage is the recharchable battery you use for the VIN Pin in this project?
I used 3.7 V Li-ion battery with TP4056 battery charger.
Hello friend, I want to carry out your project Biometric assistance system with fingerprint scanner and NodeMCU, but I want to do it with a LAMP server in raspberry pi 3B, will it be possible?
Hi, Yes, it possible.
This was so cool, but I need to add some more information when a user is logging in. For example, I want to give them an option to enter a job number (Project No) by keypad or proximity card. How can we add this option to this project? thanks in advance
Glad you liked it.
You need to modify the website to add the projects into the database in order to select the project number while logging in.
@@ElectronicsTechHaIs I meant I need a keypad beside of fingerprint senor, after the user clocks in then the user has to enter a number for example 3345, and then the log info sends to the server.
@@PayamJianTV Exactly, that isn't hard to achieve, you just need to modify the code to make work in two modes and add the keypad to enter the number. On the website side you have to add the numbers of the sections that you want.
After uploading the project is working but esp module automatically resetting itself. Not working
You´re awesome !! thanks a lot bro... You have the idea i had in mind. i´m improving your design. thinking on buy a 3d printer as well... Posting soon a response.
Glad to hear that.
Good luck.
Hi sir, may i know is there possible to make a combination of RFID and Fingerprint to this project? Means double verification in order to check in and check out, and the rest of the function is totally the same with this video, any modification of code and how is the circuit diagram. Do reply me ASAP TQ sirrrr
Does this connect automatically to USB and PC, because if you use it with another power supply, the MCU node doesn't sync with the website.
See: the USB cabe is only used to turn the ESP 32 on or to transfer data to it. Once the code is uploaded, you can charge with with an external battery or power supply without a problem. Once the ESP 32 / 8266 is on, it will try to connect the URL/ HTTP that you included in his code. The question is that the computer has to be online in order to project works, because the server / background of the system will be there. But in order to solve this you must buy an Host (like Hostgator ou Hostinger) and put the archives there like you did in the xampp folder. The example in the video is only to make internal projects.
Thank you so much bro. :)
My pleasure. Glad you liked it.
Hi Sir, thank you very much your project help me much. I wonder if I can add notification in website when the Fingerprint succesfully enrolled or reversed thing happens.

Can I use arduino uno r3? For this attendance project
Yes, but you need a wifi module to send the data to the server
Hello Sir, how are you 🙂. I have a question regarding this project. My question is...
Sir, how to send SMS (free of cost) to the parents of the students those are not attending the class.
(Sir please reply)
Thank you.
Hi, You can use IFTTT SMS service.
Or using SIM800/SIM900
What if we want to make only incoming record for each subject class. In your project it records the first entry information as incoming and second time as outgoing. Can you help me to make it keeping record for each subject?
It's record the data many times as IN and OUT.
What exactly do you want?
@@ElectronicsTechHaIs Its okay with that. But now I want to record the date and time automatically rather than inputting the date and time manually.
Is it usually takes time to downgrade the esp8266 to 2.4.1?
Yes, sometimes
Good afternoon, I have a question, do you know if you can save the fingerprint scanner information somewhere else, such as in the cloud?
Hello, You mean that if there a way to store the fingerprint image on the cloud, not into the fingerprint memory?
@@ElectronicsTechHaIs yeah, it's possible?
that depends on the fingerprint module that you will use.
can we use Adafruit optical fingerprint sensor?
Of course
