DESIGN OF AN IOT-BASED REMOTE MONITORING SYSTEM FOR YOGYAKARTA AIRPORT LOCALIZER WITH AUTOMATIC CHANGEOVER AND REAL-TIME NOTIFICATION FEATURES

This research on remote monitoring design aims to determine the condition and control the Localizer equipment in normal or alarm conditions. It can also assist in changing over during ground checks, accessible via smartphone using the Blynk app. This design uses an optocoupler sensor to detect the electrical current flowing through the LEDs on the Localizer Remote Control Unit (RCU). This allows the indicator readings to be sent to the Internet of Things (IoT) using a NodeMCU Wi-Fi module that communicates serially with an Arduino. The IoT functions to display real-time conditions and control the Localizer equipment in normal or alarm conditions, accessible via smartphone using the Blynk app. The tool I will design is an Internet of Things-based remote monitoring localizer. It is hoped that this remote monitoring tool will facilitate technicians in determining the condition of the Localizer and assist in changing over during ground checks.
