IOT Lock with Arduino and ESP8266

IOT lock composed of an arduino and ESP8266, for connection to the internet, using MQTT communication with SSL encryption for security, with this communication protocol we can access our house remotely, a clock module is also added to Obtain the exact moment of opening and who opened it, it has a fingerprint reader to facilitate access locally, however if the reader is used and it does not recognize you, an alarm will be issued to the different applications, the lock can be a simple one like the one that is placed in the prototype or a more robust one, it is quite modular since more functionalities can be added or removed.

It has a mobile application, a desktop application and a web application, any of these applications have access to both open and view the inputs or outputs, they only require an internet connection.

Both the ESP8266 and Arduino are programmed through the Arduino IDE. Instead the desktop application is programmed in Python, the mobile application is built with Kotlin and finally the web application is programmed in JS.

However, the fingerprint sensor function is that in case of not obtaining internet for some external reason, the authorized person can enter, managing to store up to 50 fingerprints.
