Automatic Ringing Door Bell: Review and Fabrication

Abstract

This study focused to compile earlier works dedicated on the development of automatic ringing door bell that have low cost and efficient life spam. Now a day’s the augmentation of such systems, among our society is high due to protection form virus like COVID-19. The contamination of surface through infected person leads to spread of virus. So, numerous of automatic systems are develop in order to protect the object from physical contact like automatic lightening systems, ringing bells, automatic closing and opening of doors, touch less water draining systems, touch free ceiling fans and many more. Among said systems, automatic ringing door bell have huge demand in every house hold due to awareness and prevention form spreading of virus. The automatic door bell beneficial to get information about the person arrived at home and without pressing the switch it will ring. The systems are based on image processing technique, machine learning approach or Internet of things for efficient functioning. Hence, in this review article, a numerous of articles are reviewed to give a conclusive remarks towards fabrication of cheap and efficient automatic ringing door bell. After discloser of efficient system gathered from earlier research work, an attempt has been made to develop a prototype of automatic ringing systems. Study reveals that the waves signals based sensor that automatically rings the bell is efficient one. Furthermore, the systems requires a PIR sensor to detect the waves signals of a person which is further transfer to activate the ESP32 cam for capturing the photo, consequently ring the buzzer. If the person is detected, the door bell is automatically turned ON and rings the bell.
