Design and Implementation of Secured Contactless Doorbell using IOT

Abstract

In this pandemic era there is a need for improved methods for contactless methods and improved technologies. We have to implement an associated M-App for contemporary house security. The “Contactless Doorbell” acknowledges an individual person standing at a set distance of 1m-2m before of the camera at that time an arduino signal is initated which in turn initiates to ring the autonomous door bell and also it initiates the Nodemcu Camera module to take the snap of the face and sends the captured image to the M-application and stored in the firebase. To build this contactless button we tend to use Arduino, NodeMCU Camera module, ultrasonic sensing element and extend the utilization of database management systems, JAVA, Computer Vision and AWS cloud services.
