Abstract
Objectives: This study aims to design an internet of things simulator of fluid volume monitoring system. Methods: The method used in this research includes simulator design and simulator testing. Monitoring system using an ultrasonic sensor, nodeMCU, ThingSpeak, and Virtuino. The value of ultrasonic sensors will be processed in the NodeMCU program resulting liquid level in the buried tank then sent through the internet to ThingSpeak. Findings: The result of monitoring the liquid level in a buried petrol station simulator uses ultrasonic sensor HCSR04P and NodeMCU v.1.0 from 08.00 pm to 02.00 am displayed on the site ThingSpeak with value 17.42 L.Setting alarm on Virtuino at 50% of maximum volume of 8.8 L. The experimental results the volume of fluid reduction 8.09 L has managed to activate alarm on the application Virtuino. Applications: This internet of things simulator of fluid volume monitoring system applicated for the petrol station underground tank. Keywords: Internet of Things, Simulator, Fluid Volume, Monitoring System, Petrol Station, Underground Tank.
Highlights
The number of vehicles in the street increases rapidly
The monitoring system designed by using microcontroller-based ultrasonic waves [5,6,7], the use of ThingSpeak as the internet of things server [8,9] as well as IP address by using a Wifi module NodeMCU [10,11,12]
This study will be designed as a system of monitoring the liquid level in the buried tank based on the internet of things, the management of fuel supply in the petrol station becomes more efficient and effective
Summary
The number of vehicles in the street increases rapidly. The petrol station facilitates the public to meet fuel needs [1]. Most of the volume examination for the availability of petrol station is conducted by measuring the liquid level manually using depth stick. Internet of things (IoT) technology serves to collect data generally by Fitria Hidayanti each of the objects connected to the internet to be processed and analyzed it into useful information and used to control and monitor these objects [2,3]. There are several previous studies that designed the tank liquid level monitoring system for the buried tank. This study will be designed as a system of monitoring the liquid level in the buried tank based on the internet of things, the management of fuel supply in the petrol station becomes more efficient and effective
