Unauthorised Area Web Security Notification System Based on Fingerprint and Internet of Things (IOT)

Abstract

The many potential uses of wireless sensor networks (WSNs) have recently piqued the curiosity 
of many in the academic world. The old wired system has become too complicated and 
cumbersome to set up, so wireless networking has taken its place. A fundamental need is the 
necessity for security and control in commercial establishments such as banks, jewellery shops, 
electronics stores, etc. Extensive coverage, dependability, remote control, and real-time service 
need modifications to the quickly growing infrastructure. By incorporating wireless technology 
into security systems, appealing advantages and an intuitive user interface may be realised. 
This article details the installation of a new security system for the surveillance of financial 
institutions. Our company locations may be made more safer and more resistant to theft and 
other criminal acts by using Zigbee network connected security measures. A number of sensors, 
a microprocessor, a voltage regulator, and Zigbee modules make up this system. Various 
sensors are set up to detect the surroundings and notify the appropriate parties via the Internet 
of Things. When the sensors detect anything out of the ordinary, particularly at night, they will 
communicate with the WiFi module over the Zigbee network. The receiver module will 
communicate with the owner or another specified recipient once it receives a signal. The 
simplicity, adaptability, low data rate, low power consumption, and dependability of Zigbee 
technology make it a popular choice. Also, customers are required to use the biometric sensor 
by placing their finger on it whenever they enter the store or property. When validated, the 
NlodeMCU microcontroller's built-in Wi-Fi module will stop the warning signals and update 
the cloud app with the information given by the user.
