IoT-Based Smart Key Finder For Smart Home Applications

Abstract

Usually, when we misplace our keys, we have to look all over the house for them before we finally locate them though not always easily. Therefore, we suggest building a basic Internet of Things key finder in this work using a buzzer, battery, and Node-MCU. The construction of a key chain that is attached to a key will be discussed in this essay. The establishment of a website devoted to the hunt for the missing keys is also mentioned in the report. The Google Chrome browser on a mobile device can be used to find the missing keys. A buzzer built into the Internet of Things keychain will sound an alert when the website locates the misplaced keys. The developed Internet of Things (IoT)-based key finder is crucial for maintaining track of the keys in addition to saving time.
