Integration of Smart Sensors with IoT Systems to Monitor Nitrogen Gas Levels in Biogas Reactors
Main Article Content
Abstract
Renewable energy is a type of energy derived from natural processes and can be used continuously. The use of new and renewable energyrepresents a societal effort to reduce reliance on fossil fuels. Biogas is one of the newest sustainable energy sources in the home.One such renewable energy source applicable at the household level is biogas, a gas produced by microorganisms through the anaerobic fermentation of organic matter. This study presents an Internet of Things (IoT)-based nitrogen gas monitoring system for determining the quantities of nitrogen gas in biogas. The hardware system for detecting nitrogen gas levels utilizes an MQ-135 sensor and an ESP8266 microcontroller for processing data via the internet or in real-time. Monitoring results indicate that the nitrogen gas concentration in biogas does not exceed 20,000 ppm, which aligns with the established standard range of 2%–5% nitrogen, or approximately 20,000 ppm. Based on these findings, the biogas is deemed to meet the required quality criteria.
