Arduino Based Security and Safety Utilities

Abstract

This paper reports two low cost, low weight, and efficient security and safe utilities using Arduino. The first one is a Fingerprint door lock system. The Arduino-based Door Access System is designed to address the problems with existing systems in terms of their upgrades and maintenance. A Fingerprint scanner is an input and the output, on the other hand, is a magnetic Solenoid lock. As when an authorized person puts his/her finger on the fingerprint sensor the door will only open for that authorized person whose fingerprint is matched with the stored fingerprint. The second system is a radical system for monitoring fish plates with help of relays and real-time signaling by detecting plate removal. The proposed system records the trains on an equivalent track using the IR module. IR module interfaced with an ARDUINO board reads the geographical coordinates of the train’s position in order that the trains are often halted by applying emergency brakes and sending signals to both the train brake and control rooms.
