DIY IoT Based Biometric Attendance Project using Arduino

In this project we use IoT to make attendance system more useful and online accessible. Most of the attendance systems generally store the information over a micro SD card and have to be connected to software via a computer to access the information.


So here we use Arduino and an IoT platform called Thingsboard to build a biometric attendance system that scans for fingerprint and on successful identification of the person it will log the information to the cloud platform ThingsBoard by using the ESP8266 Wi-Fi module. This information can then be displayed in the dashboard of ThingsBoard making it available for the required authorities to view and analysis information over the internet without having any direct physical access to the hardware.

Interesting? Follow this Circuit Digest tutorial to make this biometric attendance system project.

Below is the demonstration video of the project:

Biometric Attendance System using Arduino

There are many kinds of attendance systems are popular such RFID based attendance systems. With latest technologies there are many kind of sensors which can effectively identify a person based on their biometric featues, such as fingerprints or retina. In this project we have built a fingerprint sensor based attendance system which will make the attendance  based on the matching of fingerprints.



As shown in the above breadboard setup it uses a fingerprint sensor, LCD, buzzer, input buttons which are useful to give input and display output.
