This project is intended for construction of a Smart Fingerprint based Door Lock System, by using R307 finger print reader optical sensor module attendance scanner. The project based on the Arduino Uno/Node MCU is used for the desired purpose. A standalone module is a machine which can automatically perform tasks. 12C OLED Display Module set in front of the gate and shows the data about who is check-in with a proper ID. The fingerprint sensor detects the finger ID and give access to the 12V Solenoid lock to open the door. The project also includes Blynk IoT app which provides the remotely controlled accessed for the whole project using Wi-Fi connectivity.

3. INTRODUCTION
What is IOT?
The Internet of things describes physical
objects with sensors, processing ability,
software and other technologies that connect
and exchange data with other devices and
systems over the Internet or other
communications networks.

4. MOTIVATION
Smart home security makes use of an
assortment of IoT-enabled technologies to
enable consumers to remotely monitor and
manage the security of their houses.These
systems can control the monitoring in and
around the home, as well as who has access to
the doors if they have smart locks.
