Development of IoT based Key Finder

Abstract

Typically, we misplace our keys and hunt for them throughout the home, eventually locating them with much difficulty after a long search. Therefore, we propose to develop a basic IoT-based Key finder utilizing NodeMCU, Buzzer, and Battery in this paper. In this paper, the development of key chain which can be attached to the keys will be explained. The paper also includes the creation of a website dedicated to the search for the missing keys. The missing keys can be located using a mobile phone's Google Chrome browser. When the webpage is enabled to find the missing keys, the designed IoT-based keychain is equipped with a buzzer that will make a beep sound. The developed IoT based key finder is important in terms of keeping track of the keys and could also save time.
