Abstract

An electric vehicle uses increasing in Indonesia. Airport services are also advancing the development of electric cars on Baggage Towing Tractors (BTT). BTT is used to attract aircraft baggage to the terminal baggage queue. BTT uses an electric engine as a driving force and an 80V battery as a voltage source. If the BTT battery is not managed correctly, then it is an effect on the battery life. This battery is prone to over-voltage, under-voltage, and over-heat. The project is necessary to develop a system that makes it easier for users to monitor battery performance and technicians during maintenance. The concept of this system is based on an android application. This application will provide real-time information about battery voltage, temperature, and humidity through Firebase Database. The data received by sensors is sent to the database via a microcontroller, which is connected to a Wi-Fi network. The android application will access the database and display data in real-time by ignoring previous data. This system is designed for users to determine the condition of the BTT battery that will be used. The system was tested to evaluate measurement accuracy and speed of updating data. From the test result, the level of accuracy system is around 97%, and it’s rated as working optimally.

Abstract

Create an Internet of Things-based Air Conditioner operating system to make it easier to operate the AC. This research examines whether the system designed can transmit IR Code via IR Transmitter to AC if the device is placed at different distances. The steps to make it happen are to follow the stages of the prototyping method, which consist of gathering requirements, developing prototypes, and testing prototypes. The hardware circuit built consists of the Node MCU ESP8266, DHT 11 sensor, Infra-Red, software consisting of Arduino IDE, and blynk. By placing the NodeMCU ESP 8266 in positions with different distances, the tool can send IR Code data via the IR Transmitter to the AC, buttons on the blynk application have been made and can work according to their functions. The test was carried out with 4 different location positions, namely position 1 with a distance of 1 meter, position 2 with a distance of 3 meters, position 3 with a distance of 2 meters, and position 4 with a distance of 4 meters. From 4 test location positions with sufficient category signals to very good categories, microcontrollers can be connected to the blynk application on smartphone users. The Blynk application can function according to the commands made, the IR code can be sent through the IR transmitter to the air conditioner (AC). The DHT 11 sensor successfully measures the temperature and humidity of the air. Hopefully, in the future, the development of this tool into a multi-controller capable control not only AC but also other electronic devices.
