Biometric Attendance System with IoT

Project Description:

1. Arduino/Genuino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. Finger Print Scanner R305: The working of this module includes procedures like 1. Enrolling Fingerprint, 2. Image Processing, 3. Comparing Fingerprint, 4. Template Generating In this module there will be one high powered Digital Signal Processing chip, which will do procedures like 1. Image rendering and Calculation, 2. Feature-Finding and Searching. Because of high reliability, this module can be connected to any microcontroller or system with TTL serial, send packets of data to take photos, detect prints, hash and search. This module can be used to enrol new fingers up to 162 finger prints. There is a red or green LED in the lens that lights up only during a scanning process.
3. LCD Display 16*2: Generally we use LCD to display the limited set of output statements. At present we use mostly 16*2(4 bit communication) and 16*4(8 bit communication), which means 16 letter spaces with 2 lines and 16 letter spaces with 4 lines(each line will have 16 letter spaces)
4. Wi-Fi Module: ESP8266 Wi-Fi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter.
5. SPST Switch: SPST Switch abbreviated as Single Pole Single Throw Switch. Here Pole refers to the number of circuits controlled by the switch (SP switches control only one electrical circuit)and Throw refers to the extreme position of the actuator (ST switches close a circuit at only one position) The other position of the handle is Off.

Project Implementation:

1. The Finger Print Sensor is interfaced with the Arduino board
2. At the beginning, your finger will be scanned by placing your finger on the scanner
3. Once your finger is scanned, the scanner will generate template by Image Processing method which will be stored for comparing
4. Like this we will store all the templates of different people
5. So when we place our finger, the scanner will scan the finger and it will generate template and this template will be compared with previously stored templates
6. If both templates are matched, then certain people data stored will be shown on the LCD
7. The data regarding how many students were present on day to day basis can be updated in remote cloud rather maintain ledgers and record books and can be retrieved whenever we want

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
2. Thingspeak : Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online
