IOT BASED DOOR ALERT SYSTEM FOR PEOPLE WITH HEARING IMPAIRMENT
Abstract
Persons with hearing impairment face many challenges every day in their life and the biggest challenge they face is communication. They face difficulties in getting and giving information, exchanging ideas, sharing their feelings in a group or even in a one-to-one contact. There are many devices and systems that are available to assist deaf and hearing impaired people to improve their communication and to adapt to the environment and society more effectively. The paper deals with designing and implementation of low cost device for people with hearing impairment who live alone and independent to get notified when the door-bell rings. The system consists of Raspberry Pi, Raspberry Pi camera, Vibrator, Server motor, ADC board, LED board, WIFI module and Bluetooth module. The evolution of technology has reached to an extreme horizon that makes the life for an ordinary human being easier. In such scenarios, the technological stream of Internet of Things(IoT) plays a major role to help the individuals in various ways. The latest evolution of Internet of Things is Raspberry Pi model B 3 which is utilized to its extent to serve the human race with all the embedded features in it. The Raspberry Pi is a low cost, low power embedded controller which consists of features like WiFi, Ethernet connection port, in-built Bluetooth, manageable USB ports and changeable OS specifications. The complete system consists of transmitter and receiver. The transmitter section includes Raspberry Pi, Raspberry Pi camera, switch, WiFi and Bluetooth. The receiver section includes wearable vibrator which provides alert to the hearing impaired person. The system upon receiving alertness through vibrator, person checks the mobile phone and is able to determine the details of the person arrived. The software used for this work is python, PHP/ MySql and android app. The employed device consists of a well built and configured OS on its latest version of Raspbian. The Raspbian OS and other configurations are specified on own terms as the device is expected to work. The Raspberry Pi board is connected to the devices and components such as Raspberry Pi Camera(PiCam), the display, Ethernet for internet access and the server motor. The programming languages like Python and Kernel are used to configure Linux commands in this work
