FINGER PRINT AND IOT BASED SECURITY ALERT SYSTEM FOR UNAUTHORIZED AREA USING WSN

Abstract

Recently wireless sensor networks (WSNs) have appealed a great deal of interest in the research community due to its wide variety of applications. Wireless networking replaces a wired system which has become very complex and hard to set up. Security and control for business places like banks, jewellery stores, electronic stores etc. is one of the basic needs. But the rapidly evolving infrastructure needs to be modified to ensure extensive coverage, reliability, remote control, and real-time service. Attractive benefits and user-friendly interface can be achieved by deploying wireless technologies for security system. In this paper, implementation of a novel security system for banks monitoring is presented. Using Zigbee network enabled technology, we can make our business places more secure and provide high level of security against robbery and other malicious activities. This system consists of Zigbee modules, microcontroller, voltage regulator and various sensors. Different sensors are deployed to sense the environment and send alert notifications through IoT to the concerned people. The sensors would sense abnormal activity especially at night and send signals through the Zigbee network to WiFi module. After receiving signal at the receiver module, it will send message to owner or any other required destination. Zigbee technology is used because of its reliability, low power consumption, low data rate, simplicity and flexibility. In addition to that, when a person enters into the shop/premises he/she need to place their finger on the biometric sensor. If it is identifies then the alarm signals will be deactivated and the person who entered that information will be update in the cloud app using internal Wi-Fi module of the NlodeMCU microcontroller.
