Methane Gas Measuring Instrument In The Biogas System To Determine The Energy Value Produced Based On Arduino Nano
Introduction
Biogas is a mixture of gases consisting of methane (CH4), carbon dioxide (CO2), and other gases produced from the decomposition of organic matter, such as animal waste, human waste, and plant residues, through the activity of methanogenic bacteria. To produce biogas, the organic material is processed in a biodigester. The decomposition process takes place anaerobically, which is without the presence of oxygen. Various sources of organic material, such as market waste, leaves, and animal feces from cows, pigs, goats, to horses, can be used as raw materials to produce biogas, even human waste can be used. The composition of the gas produced varies depending on the type of organic material used in the process.
One challenge in managing the biogas system is to measure the concentration of methane gas produced, because methane is the main component that provides energy value to biogas. For this reason, an accurate and efficient measuring device is needed. One modern solution is to use Arduino Nano, an electronic platform that is very flexible and easy to use.
Arduino Nano's Advantages of Measurement of Methane Gas
Arduino Nano is a microcontroller board that is small and practical, making it suitable for sensor-based applications. By using Arduino Nano, we can make methane gas measuring devices that are able to provide data in real-time about methane concentration in the biogas system. This data is very important to optimize the biogas production process, as well as to ensure that the gas produced has maximum energy content.
Main Components of Methane Gas Measuring Devices
In making Arduino Nano-based methane gas measuring devices, there are several important components needed:
1. Gas Sensor
A gas sensor, such as MQ-4 or MQ-7, is used to detect methane gas concentrations in the biodigester. This sensor will provide analog signals related to gas concentration.
2. Arduino Nano
As the brain of the system, Arduino Nano will process the signal received from the sensor, then change it into a gas concentration value that can be read.
3. LCD Display
To display the results of measurement visually, we can use LCD. This allows users to view information directly without the need to connect to the computer.
4. Other Components
Other components, such as a power supply, a breadboard, and jumper wires, are also needed to complete the system.
Work Process Measuring Tools
The work process of this tool is quite simple. First, the gas sensor will detect methane levels in biodigester. The data obtained will be sent to Arduino Nano to be processed. After that, the measurement results will be displayed on the LCD, so that users can immediately find out the concentration of the methane gas produced. With this information, the owner of the biogas system can take steps to optimize the process, such as adding organic matter or regulating biodigester temperatures.
Analysis of the Benefits of Using Arduino Nano-based Methane Gas Measuring Instruments
Using Arduino Nano-based methane gas measuring devices offers various benefits. In addition to the relatively affordable cost, this tool also provides convenience in maintenance and use. The accuracy of the resulting data is very important to increase the efficiency of biogas production. In an era where renewable energy is increasingly needed, biogas as an alternative energy source must be utilized optimally.
With a good monitoring system, we can prevent energy losses due to gas production that is not optimal. In addition, by utilizing simple technology such as Arduino Nano, we can make this measuring device itself, thereby reducing dependence on commercial devices that are often expensive.
Conclusion
The development of methane gas measurement equipment in the Arduino Nano-based biogas system is an innovative step in an effort to improve the efficiency of biogas production. With this tool, we can not only monitor methane concentration, but can also optimize the fermentation process so that the maximum energy value produced. The existence of this tool can contribute greatly to the management of organic waste and more sustainable renewable energy development.
