Abstract

Fire & gas safety control is a control system to secure a room / building from the danger of gas leakage or fire. In the current era, the development of building architecture requires us to always innovate in maintaining the safety of the occupants or the building itself. This research makes an Advance Fire & Gas Safety Control tool which aims to minimize false alarms, especially regarding steam. Smoke and steam can be distinguished by the level of humidity. Smoke, which is particulate matter, has a very low humidity level, while steam has a very high humidity level. This research implements NodeMCU ESP8266, MQ-2 Sensor, DHT11 Sensor, Fire Sensor, Buzzer, Firebase and Kodular, to detect fires, steam and gas leaks.

Abstract

Pada zaman sekarang, perkembangan teknologi semakin pesat sehingga banyak perusahaan yang sudah mengganti presensi manual menggunakan presensi otomatis. Tetapi masih ada juga perusahaan yang menggunakan presensi manual menggunakan kertas. Tak terkecuali di PT. Urban Asia Industri yang masih menggunakan presensi manual dalam pengambilan makan siang. Untuk itu  dibuatlah rancangan sistem presensi makan siang yang bersifat otomatis menggunakan mikrokontroler dengan tambahan sensor Radio Frequency Identification (RFID). RFID adalah teknilogi untuk mengidentifikasi yang berbasis nirkabel (wireless) yang memanfaatkan gelombang elektromagnet dengan frekuensi tertentu untuk mengambil data dari suatu objek. Sensor RFID terdiri dari dua komponen utama yaitu RFID Reader dan Tag RFID. Perancangan sistem absensi makan siang pada PT. Urban Asia Industri dilakukan dengan mengidentifikasi masalah yang terjadi di lapangan. Rancangan sistem absensi makan siang ini terdiri dari dua rancangan yaitu rancangan hardware dan rancangan software. Hasil pengujian dari hardware dan sorfware yang telah dilakukan sesuai dengan yang diharapkan dan dapat bekerja dengan baik.

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.
