An Improved Design of Smart Alarm System for Hearing Impaired People using Arduino

About nine million people in the world are considered to be a hearing impaired people. Communications between hearing impaired peoples and a normal person have always been a challenging task. This lack of communication can be minimized or rectified by using suitable technologies. Thus developing such a technology which is connecting the hearing impaired people and normal people are necessary in this situation. This project work represents the design and construction of smart alarm system for hearing impaired people. The inconvenience caused to the people standing outside the door seeking for the response from the hearing impaired person who is inside. This system consists of Arduino Microcontroller for controlling all the operations. Vibration motor which is fitted as a smart band on hearing impaired person wrist which is used to notify the person is standing outside. Camera paired along with this system used to see and monitor the person standing outside. Along with this DC Gear motor coupled for automatic opening and closing of doors.
