Construction of a Smart Home Automation System With Voice Activation and Fingerprint Security System

Abstract

In this project, voice is used to operate switches. The reason for selecting speech is that it is readily replicated by humans. Furthermore, the use of expression provides an effective and simple control system. The implementation of this mechanism entails changing the switching system from the conventional method of physical interaction with the switch to a safer method in which voice replaces all physical contact. Home automation refers to building automation for a residence, also known as a smart home or smart house. Which includes the control and automation of lighting, heating, ventilation, air conditioning, and safety, as well as home appliances such as ovens and refrigerators/freezers. Bluetooth, WIFI, and GSM are only a few examples of wireless infrastructure. This paper introduces new designs and various home appliances. The ability to monitor the lamp using a mobile phone device with Bluetooth wireless technologies is the home automation application discussed in this article. The relays are used to link these appliances to the board's input/output ports. For this use, the architecture is low-cost, modular, and employs new technologies and devices. The use of a wireless Bluetooth connection in the control board enables a simpler interface implementation. Adding various sensors like gas sensor, temperature sensor, LDR and PIR sensor to the mix also made the whole system more unique and versatile. The system has been successfully built and operated.
