IoT Based Biometric Fingerprint Attendance System with NodeMCU ESP8266

....................................................................................................................................................................................................................................
In this project IoT Biometric Project, we will learn how to build IoT based Biometric Fingerprint Attendance System using NodeMCU ESP8266 12E, 0.96” OLED Display & R305 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 R305 or R307 or any other compatible Fingerprint Sensor and verification is done on the client with the transmission of fingerprint templates over the network.
The website that is coded in PHP 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.
The Source Code/Program, library, circuit diagram & connections all can be downloaded from the website link below. The programming can be done via Arduino IDE.

The most easiest and correct explanation I had ever seen

[@sahilkamble8750]

Hey Hii Have you got the output of that fingerprint sensor??

[@nikomoattana1529]

Hello sir, I saw a video on KZbin, the video was about a biometric attendance system using a fingerprint scanner and NodeMCU with a database & 3D printed casing. I want to ask whether this connects automatically with USB and PC, because if you use it with another power supply, the nodeMCU doesn't sync with the website.

[@sharanya4927]

Sir do u have connection video of biometric attendance using gsm module too? The same connections only and additionally we'll be using gsm ...

[@jahidul_islam_60]

HELP ME....!!!! I'm facing a very annoying issue here.... whenever I'm trying to enroll a fingerprint through database (e.g 7:39 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... (I've checked fingerprint enrollment in the arduino example code...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....)
