Abstract
With increasing popularity of the IoT (Internet of Things) and devices getting smarter day by day, this paper presents an
idea to reform the existing access control systems. This approach of enhancing the access control system ensures that the
system is wireless thereby reducing wiring issues. The prototype described in this paper has the provision of accepting
inputs from a smart card reader (RFID reader) or a biometric sensor. These inputs are processed inside the controller
(TM4C123GXL-based on ARM Cortex-M4). If the inputs are found to be valid, access is granted to the user and the logs
are wirelessly transmitted to the computer using a WiFi module (CC3100). Machine learning algorithms are
implemented to monitor and analyse collected data.
Keywords: IoT, Access Control , Security, Wireless, WiFi, Machine learning.
1.Introduction
1With increasing demand from the industry for better
access control systems, this paper is an attempt to make
the conventional access control systems smarter and
thereby decreasing the risks of breaking in into the places
where these access control systems will be installed. EKTM4C123GXL
is the development board which is used.
Data from RFID reader and Biometric sensors are serially
transmitted to the microcontroller. If valid fingerprint data
or valid card no. is received, the microcontroller sends a
signal to the WiFi module1. The WiFi module2 present at
the door receives that signal and trips the relay according
to the signal received. This is how the door opens. Also
the WiFi module sends a signal to the PC via the same
WiFi network. Hence the logs of people trying to access
the door are maintained in the PC
4. Extensions to the Main Project
Given the advantages of any wireless network, a wireless
access control system can be enhanced by adding a lot of
additional features. Some of them are listed below:
1. Machine learning can be implemented and make the
system smarter. It can be used to analyse timings and give
access in the future. Apart from this, the data collected can
be used to monitor the efficiency of workers.
2. A camera can be implemented connecting it wirelessly
to the WiFi module, adding a second layer of security. A
photograph can be clicked and sent on the server via WiFi
every time the sensor comes across new data (entrant).
3. Wireless access control can be used in college
classrooms to take attendance and also keep parents
updated about pupils' attendance records. WiFi will help in
transmitting attendance records on the server.
