ILS ROOM TEMPERATURE MONITORING AT JUANDA AIRPORT WITH ANDROID IOT BASED USING MESSAGE QUEUE TELEMETRY TRANSPORT PROTOCOL

Abstract

Room temperature monitoring Instrument Landing System (ILS) is critical to keep the equipment working correctly. So that the airplane that will land can receive a good signal and the landing can be carried out perfectly. Remote monitoring must be done in real-time and continuously. Therefore data retrieval is also done wirelessly. So that only sensor equipment and transmission systems are on site. By utilizing the Message Queue Telemetry Transport (MQTT), a simple message protocol that can publish and subscribe. The MQTT protocol is designed to be open and easy to implement, capable of handling thousands of remote clients with only one server. MQTT minimizes network bandwidth and device resource requirements. This approach makes the MQTT protocol very suitable for connecting machine to machine. During the performance of the tool, an internet connection must be connected. The DHT11 sensor module retrieves the temperature value in the ILS chamber. Furthermore, the temperature value is sent by the NodeMCU to the MQTT server and displayed on the smartphone and the MQTT-Dash Android application
