In the present day, the process of receiving important mail or parcels still relies heavily on manual checking, which can lead to delays or missed information. This research aims to design and develop a prototype of a smart mailbox that provides automatic notifications powered by alternative energy, utilizing Internet of Things (IoT) technology to enhance convenience, security, and accuracy in mail detection. The prototype system comprises four main modules: (1) a power supply unit utilizing solar-charged batteries, (2) a central control unit based on the ESP32 microcontroller, (3) a sensing unit capable of detecting mailbox openings and motion, and (4) a notification unit that automatically sends images and alert messages via the LINE application. The system was deployed and tested in a real-world environment under various conditions. Key performance indicators included detection accuracy, notification response time, and energy efficiency of the alternative power source. Experimental results demonstrated that the system operated accurately and reliably, achieving 100% notification accuracy and maintaining sufficient battery charge for daily operation without external power sources. The findings indicate that the proposed smart mailbox has strong potential for practical implementation. It effectively reduces the burden of manual mail checking, enhances user convenience and security, and can be integrated efficiently into modern smart home ecosystems.
