Home Security And Automation Using NodeMCU-ESP8266

Protection of our personal properties is a key challenge and prior responsibility every time which affects massively on a day to day life. The current system of achieving security has plenty of drawbacks and less secure. The main goal of implementing a home security and automation system is to achieve a powerful and more secure way to handle the day to day stuff preventing from misuse hands and keeping track of usage of home electrical appliances to know the necessary and unnecessary actions. The system is built on IoT (Internet of things) to make more accurate and error-free control over the flow of the system. To make the difference from the existing system, in this proposed system we built the communication of hardware devices with a web application where devices take commands and operate it while web application rise the commands and keeps track of each transaction made so far. The combination of hardware and software will make life easier and safer for its users.

I. Introduction

The home security system is an idea of lock/unlock and turn on/off devices of home appliances through using microcontroller NodeMCU ESP8266, fingerprint sensor, solenoid lock and web application, where it becomes more trustable and feel more secure. The direct benefit of this system is zero redundancy, no duplicate fingerprint access can happen, saving them time and cost.
