Implementation of Interface & Data Acquisition System for Biogas IoT Monitoring System

Biogas is a type of renewable energy that has a very large production potential in Indonesia. However, biogas production still has some significant problems, such as the production is less efficient, cannot be produced in large quantities, takes a long time, and has the probability to fail if not monitored regularly. Therefore, a monitoring system for temperature, pH level, and gas pressure parameters from biogas production based on the internet of things is proposed. One part of the system is data acquisition with sensors and the interface of the designed system. In its implementation, the parameter measurement will use the DS18B20 as a temperature sensor, SKU SEN0169 as a pH sensor, and MPX5010dp as a gas pressure sensor. The interface will be divided into two: the site interface in the form of an LCD, LED, and a button, and an off-site interface in the form of a web application designed with React JS. The developed product will be provided with a unique ID and password to access the parameter data dashboard on the web application. In general, functional testing for each module has been successfully carried out and it produces satisfactory results with measurement errors below 3% and data can be displayed in a progressive web application.
