Perancangan Sistem Identifikasi NodeMCU ESP32 Terhadap Perangkat BLE

Abstrak

An identification system is a system that is used to find out information. With the development of increasingly sophisticated technology, the identification system can be carried out automatically in order to assist in carrying out work to be lighter, more effective, efficient, and accurate. By utilizing wireless technology that is widely used by the public, an automatic identification system can be carried out by employing devices that have wireless networks such as Bluetooth Low Energy (BLE). In this study, testing was carried out using the NodeMCU ESP32 microcontroller on BLE iTag Smart Bluetooth devices. The test generates an RSSI value to measure the tool's ability to detect BLE devices. After conducting research, it can be concluded that the tool can detect BLE iTag Smart Bluetooth devices stably at a distance of 1-2 m with an average RSSI value of ???? 66 dBm. The RSSI value can also provide an estimate of the distance from the BLE device, in this study the difference between the range of 1-5 m and the estimated distance has a slight difference.

Sistem identifikasi merupakan sebuah sistem yang digunakan untuk mengetahui sebuah informasi. Dengan perkembang teknologi yang semakin canggih, sistem identifikasi dapat dilakukan secara otomatis agar dapat membantu dalam melakukan pekerjaan menjadi lebih ringan, efektif, efisien, dan akurat. Dengan memanfaatkan teknologi wireless yang banyak digunakan masyarakat, sistem identifikasi secara otomatis dapat dilakukan dengan memanfaatkan perangkat yang memiliki jaringan wireless seperti Bluetooth Low Energy (BLE). Pada penelitian ini dilakukan pengujian menggunakan mikrokontroler NodeMCU ESP32 terhadap perangkat BLE iTag Smart Bluetooth. Pengujian dilakukan dengan menghasilkan nilai RSSI untuk mengukur kemampuan alat dalam mendeteksi perangkat BLE. Setelah melakukan penelitian, dapat disimpulkan bahwa alat dapat mendeteksi perangkat BLE iTag Smart Bluetooth secara stabil dengan jarak 1-2 m dengan rata-rata nilai RSSI ???? 66 dBm. Nilai RSSI juga dapat memberikan estimasi jarak dari perangkat BLE, dalam penelitian ini selisih jarak jangkaun 1-5 m dengan estimasi jarak memiliki selisih yang kecil.
