The Smart Detector is a low-cost electronic device designed to help users quickly locate misplaced items such as keys, remotes or small bags. The system works by detecting a whistle sound using a sound sensor, which triggers a microcontroller to activate a buzzer and LED indicator. This allows the missing object to be easily found without the need for smartphones, internet or mobile applications. The project promotes creativity, innovation and problem-solving by offering a simple and practical solution for daily challenges. Overall, the Smart Detector is user-friendly, accessible and demonstrates the effective use of sound sensor technology in real-life situations.
