Abstract

In hydroponic cultivation sites, pH control is still carried manually by checking the pH level with a pH meter and providing a pH balancing liquid manually. This study aims to design an automatic pH control system in the Deep Flow Technique (DFT) hydroponic system that uses the Internet of Things (IoT) based Fuzzy Logic Controller (FLC). The SKU SEN0161 sensor detects the pH value as FLC inputs in an error value and its changes. These inputs are processed using Mamdani FLC embedded in the Arduino Mega 2560 microcontroller. The FLC produces an output in a pH liquid feeding duration using the peristaltic pump. The results showed that FLC could maintain the pH value according to the set point with a settling time of less than 50 seconds, both with disturbance by adding pH liquid and without disturbance. The pH value can also be displayed on the website interface system as a monitoring system.

Abstract

This research aims to design fire early warning system using Arduino and Android with Bluetooth communication. The system is constructed using three sensors which are KY-026 flame detector, DS18B20 temperature sensor, and MQ-07 gas sensor. The communication used HC-05 Bluetooth module to send sensor data from Arduino to Android. Testing results show that Arduino through Bluetooth communication able to send sensor data to Android within range of 20 cm with no obstacle condition and range of 10 cm if there exists the obstacle. The system will send ‘normal’ status to Android when fulfilled this conditions: flame sensor value less than 200, temperatures less than 30°C, and gas levels less than 300 ppm. There are seven other conditions that contain ‘warning’ and ‘danger’ data if those condition above not fulfilled.

The system is constructed using three sensors which are KY-026 flame detector, DS18B20 temperature sensor, and MQ-07 gas sensor. The communication used HC-05 Bluetooth module to send sensor data from Arduino to Android. Testing results show that Arduino through Bluetooth communication able to send sensor data to Android within range of 20 cm at no obstacle condition and range of 10 cm if there exists the obstacle. The system will send ‘normal’ status to Android when fulfilled this conditions: flame sensor value less than 200, temperatures less than 30°C, and gas levels less than 300 ppm. There are seven other conditions that contain ‘warning’ and ‘danger’ data if those condition above not fulfilled. Penelitian ini bertujuan untuk merancang detektor dini kebakaran menggunakan Arduino dan Android dengan komunikasi Bluetooth. Sistem dibuat menggunakan tiga sensor yaitu sensor api KY-026, sensor suhu DS18B20, dan sensor gas MQ-7. Komunikasi menggunakan modul Bluetooth HC-05 yang berfungsi untuk mengirim data sensor dari Arduino kemudian diterima Android. Hasil pengujian sistem menunjukkan bahwa Arduino melalui komunikasi Bluetooth dapat mengirim data ke Android dengan jarak 20 meter jika tidak ada hambatan dan jarak 10 meter jika ada hambatan. Apabila nilai sensor api kurang dari 200, suhu kurang dari 30°C, dan kadar gas kurang dari 100 ppm maka sistem akan mengirim status ‘normal’ ke aplikasi Android. Jika kondisi tersebut tidak terpenuhi, maka ada tujuh kondisi lain yang berisi peringatan ‘warning’ dan ‘bahaya’.
