Contactless Doorbell System

Project Code :TEMBMI2243

Objective

The main objective of this project is to avoid contact while pressing door bell. The presence of a person within one metre will be identified and an alarm will be generated to alert people in the house.

Abstract

Due to the raise in covid19 cases, touching object in the new place is not recommendable even though it might be a door bell. This project gives us an alert when a person comes nearer (i.e. lesser than 3ft) to the door. And it is a portable device; one can easily attach it to door. An ultrasonic sensor is used to measure the distance and if it detects a person within 3ft, buzzer alert will be generated.

Keywords: Arduino Nano, OLED, Ultrasonic sensor.

NOTE: Without the concern of our team, please don't submit to the college. This Abstract varies based on student requirements.
