Define the problem & relevance to today’s market/society/industry need

Technology has been a boon to the human life for betterment, security and advancement

especially with the invention of cars on 1886, through which people could locomote and

move from one place to other faster and in a secured manner and cover long distances,

take a halt to rest in between their journey wherever they feel like and spend a good time

with family and friends through road trips and most importantly it became a symbol for

status and recognition, but back then there was a problem they didn't have proper locks

for the doors. In 1914, the invention of power locks made the car even more secured and

easier to access using NFC chips in order to avoid delay of the user or jam of the manual

lock of the car door. The mechanism, the actuator, that are responsible for the constant

locking and unlocking are designed to be reliable. Many newer cars have four or five

different ways to lock the doors and the car must keep track of the multiple signals that

communicate that the car should be locked or unlocked.

And with proceeding number of days and technology, we need better security for

everything around us because the probability of theft is always high.

Propose the solution to Problem Identified

● A biometric sensor operating as a door lock for the car making them

secured and privately owned by the user. Deploying the application of

IoT embedded with fingerprint scanner, the power lock gets even more

stronger and secured and keypad can be replaced with a software

application tool, which would not only allow to break into the doors lets

the user know where had they had parked the car.

● Therefore, we use IoT Based Biometric Security System using the

GT5111C3 fingerprint sensor, NodeMCU and Solenoid lock. Adafruit IO

is used to save the entry details online while IFTTT is used to send the

Email notifications when an unauthorized person scans the finger on

the fingerprint sensor.

How is your proposed product/ process/service being different/ better from a similar

product/ process/ service, if any, in the market

The product can be a very new entry to the market and develop a good niche although, there exists products which has fingerprint scanners mounted on laptops and mobile phones mostly on digital embedded device but not at any automotive-mechanical device.

If your Idea is technology based, then specify the TRL Level (Technology Readiness Level-refer annexure ) and Expecting the features of Idea/PoC. TRL 0 The circuit for IoT based Biometric Security System consists of a NodeMCU, GT511C3 Fingerprint Sensor, Solenoid Lock, Relay Module and Buzzer. VCC and GND pin of Fingerprint sensor are connected to 3.3V and GND pin of NodeMCU while TX and RX pins are connected to D6 and D5 pins of NodeMCU. Positive pin of the buzzer is connected to D2 pin of NodeMCU, and the negative pin is connected to GND of NodeMCU. The solenoid lock is connected to NodeMCU through the relay module. The NodeMCU and Solenoid Lock both are powered with 12V Adapter.

OPERATIONAL PRINCIPLE ● (^) The circuit for IoT based Biometric Security System consists of a NodeMCU, GT511C Fingerprint Sensor, Solenoid Lock, Relay Module and Buzzer. VCC and GND pin of Fingerprint sensor are connected to 3.3V and GND pin of NodeMCU while TX and RX pins are connected to D6 and D5 pins of NodeMCU. Positive pin of the buzzer is connected to D2 pin of NodeMCU, and the negative pin is connected to GND of NodeMCU. The solenoid lock is connected to NodeMCU through the relay module. The NodeMCU and Solenoid Lock both are powered with 12V Adapter. ● (^) Once the Code and Hardware are ready, we can check if everything is working or not. Upload the code to NodeMCU and connect it to Adapter. Now, wait for Wi-Fi connection. Once the NodeMCU connects to the Wi-Fi, scan your finger on the fingerprint sensor. If the finger is enrolled, then it will open the lock with a beep sound, and it will send a message with the person’s name through the gateway. And if the finger isn’t enrolled, then it will send an email to the associated email address that an unauthorized person tried to enter.

RESULT

● (^) For fingerprint ad verification to unlock the car door: https://github.com/AnkitPradhan26/fingerprintscanner_ElecS ● (^) Geostationary location of the vehicle: https://github.com/traccar/traccar ● (^) As one enters the application the user is asked to register the fingerprint and select the car model in order to register the number of users as per that. ● (^) The door unlock operates only when one of the registered users from the database access the door and when it verifies one of the entries, it allows, ● The app also gives access to the location of where the car has been parked and who had been accessing it time to time.
