ABSTRACT
We realize we've misplaced our keys and are frustrated by a massive search of the house. This paper develops a simple IoT-based key discovery method that uses a NodeMCU, a buzzer, and a battery. The method involved creating a key management method designed for key installation and developing a website to assist with key location. With her Google Chrome browser on the user's mobile phone, she can pinpoint the location of the lost key. When the website presses the key search button, it will play an IoT key-related beep and save time by streamlining the process. If you misplace your keys, you may search all over the house, but in the end, you may not be able to find them. This paper is extremely important in that it has developed a method for quickly finding keys using the method described above.
