Portable IoT based fingerprint biometric attendance system using NodeMCU
HTML-код
- Опубликовано: 3 окт 2024
- In this video, I will tell you how to build a Portable IoT based Fingerprint Biometric Attendance System using NodeMCU ESP8266 12E, 0.96” OLED Display & SFG R303a Fingerprint Sensor. The ESP8266 Wi-Fi Module will collect the fingerprint data from the multiple users and sends it over the internet to a website. The Enrolment of fingerprints is done on the server using any fingerprint sensor like R303, R305 or R307 that is available on the market and verification of the fingerprint will be done on the webserver while fingerprint templates are transmitted over the WiFi.
The website used in this project is developed using PHP, it has a database and records of attendance. By logging into the website, you can collect all the attendance records of each user including personal details as well as incoming & outgoing timing. The data can also be downloaded and exported to an excel sheet.

Can I use arduino behalf of node MCU & in which line of code I will have to rectify for that...Thanks in advance you are doing great job keep making such amazing videos 👍
Nice project 👍
the above code gives error ": control reaches end of non-void function [-Werror=return-type]"
Can you please give me the full code ... please give me it's urgent
hello sir, what shoud i do? if i have notice like this
exit status 1
'amp' was not declared in this scope; did you mean 'map'?
I got thi same error. Did you solved now.?
The requested URL was not found on this server.

sir this error is showing when i am runing localhost
Did you get the solution for this problem brother?
hai sir..i already done all the connection and it works perfectly and knows I'm facing a new problem which is when I want to add a new fingerprint through the webpage I cannot add it, plus the screen on OLED doesn't display the scanning part such as on your video at minute 6
may I know how can I solve this problem? thank you, sir.
I have same issue ... If u find the solution plz share
bro ada buat tak? dan siap ke?
Afternoon
Please you have the solution?

Thank you for your support.
sir my attendance is not being marked, its registering student finger print id but not marking attendance what could be the possible mistake we are doing please help me
hi its possible to integrate the apps time attendance to biometric device?
I want to add a ethernet port with this setup to get connection through wire. can i add ethernet to this setup? if yes how can i add? is there anything should i change in the code for add ethernet. Wifi is not stable thats why im looking for a ethernet option. and also i have multiple wifi connections if one connection fail i can use other. is there any option to add multiple wifi connection to the nodemcu by changing the code?????

I'm getting this error, please help me sir
Hello after i enrolled my fingerprint i can log in.. how to fix this?
please my final year project is in 1 month and i want to use this. Can i?
Sure, you can use.
@@electronicsinnovation Ok thank you very much. i will use it and if i come across something, i will let you know and when i am done i will make a donation to your works. Thanks.
@@electronicsinnovation and i have a question, will be able to implement filtering? such as absentees and timing
Electronics Innovation and please what’s your email
Timing feature is already there. Absenteea feature you can add, if you wish.
unable to add finger print(enroll users) . kindly guide

Hi, I have two fingerprint modules.
The r307 fingerprint module says it's found but the led light won't light up or do anything else.
The other one, a DY 50. The led lights up but it won't find the fingerprint sensor.
Help me please. :(
I think r307 is working fine, if your serial monitor is showing the sensor work then it should work, coming to the led it glow on certain condition only(sensing a finger print), may the the special condition is not satisfying to glow led. or the led may damaged. you don't have to worry about that led is just a indication to let you know the certain action is happening with sensor, try again to register and validate the finger prints.
then let me know if you have any issues???
Coming to DY50, May be the TX and Rx pins are reversely connected or not properly connected. so verify the hardware connections and let me know if any issues....
Sir you are great❤❤❤
How to connect pc(computer) with node mcu?
I have old PC without wifi and bluetooth
You can use USB
@@electronicsinnovation
Sir
I am talking about how to take attendance log.
Via PC (without wifi,bluetooth connectivity)
Hy brother how to send fingerprint data to Firebase database using nodemcu esp8266.
Please reply.
can you adding a person picture to this project. i mean, after a person done thumbprint the data will show approved. at the same time the data will show our pictures.
No finger in the fingerprint sensor but error is delete the finger from the scanner? Please reply soon as possible
Sir please make detailed video on circuit diagram we are confused please please please 🙏 sir
Sir, can u explain sql error?
Bro were u able to solve this error
Please reply bro
Hi, Can I saved the fingerprint template into database and then compare fingerprint scanned with the fingerprint saved?
Is a pc is mandatory for this realtime working??
The display is just showing connecting here. Please What can be the problem?
HELP ME....!!!!
I'm facing a very annoying issue here....
whenever I'm trying to enroll a fingerprint through database (e.g 6:15 in the video) , my fingerprint sensor is supposed to blink continuously for scanning a fingerprint as we see in the video...
BUT, my fingerprint sensor is not responding correctly at all.. rather it blinks about 11s periodically without enrolling the fingerprint...
(I've checked running fingerprint enrollment code from arduino example....In that code the sensor works fine... it blinks continuously for scanning...But in this code the sensor is not blinking as it should be....)
Hi sir are you done with your project? I needed some help in it can you please help me
Can I use TX0 and RX0 instead of TX2 and RX2? please do reply, this is urgent.
please sir give me the link of code file
i want to learn more from you on this project.
Sir given program contain so many errors
can i get the code file link
Http begin(link)error
is there a tutorial on how to do the wirings?
I not find database
Sir I found Error"Did not find fingerprint sensor".. Could you please help with this problem?
Same issue
I'm having the same issue, but when I used Arduino board to run the test, the fingerprint was found. What could be the issue?
I have a doubt
How the code data u entered is connected to the device directly
didn't under stood your question, you mean how the people registration is happening???
how to register new employee or student after real implementation is completed (registration is required connecting the device with the computer by USB cable or not)
Registration process is completely wireless, you make sure you device and laptop connected to same WiFi network and the xampp server is running.
@@electronicsinnovation ok thanks, i have one other question that is consider you use the node MCU for your project unfortunatly you want to use that Nod MCU for other project it is posible or not (it is posible to use one nod MCU board for different projects)
@@MeZotubeEthiopia yes, you can use.
@@electronicsinnovation ok thanks if i have question i will email you
Bro did you make this?
"You can't add add more than 1 id each time " this come always while i trying fingerprint id to the database
That means you have added I'd but you didn't give fingerprint. Kindly give you your fingerprint for two times then you can add another Person.
Every time you add I'd and link with finger print and add another. untill and unless you didn't link with finger print it will not move further.
@@electronicsinnovation fingerprint doesn't scan for any id and also newly added user name and data do not add up to the user manager section.how to solve this issie ?
Did you solve the issue?
Code Error Coming What I do Anna....😔
Bro php sources enga?
Yes bro.. Do you solved errors now.?
Thanks for tutorial . Can i keep the data on firebase rather than using xampp with this hardware?
Yeah, You can...
@@electronicsinnovation how did you connect the battery on power supply circuit? just soldering to wires on battery poles? i am a newbie :(
@@rumeysakarakavak9346 Yeah, I have just soldered two wires on both poles of battery, You can follow this if you wish to. Or there is a battery holder on the market you can use that too.
what if i have to add more than 127 users ?? how can i do it ?
The Storage capacity Fingerprint sensor is up to 150 unique fingerprints, You can increase up to 150 only. But I have developed a program for 127 Fingerprints prints only, If you wish to increase up to150 you can do it by simply edit the code.
@@electronicsinnovation isn't it possible to store the fingerprint in an external database and store a lot more than that? 150 is just too small. There has to be a way.
@@stylishhughes You have to check with other advenced finger print sensor modules. I think that feature was not there with current module.

why this
what is differ from pin 2 and 3
pleas replay faster
and why 127 finger only
