Implementation of Data Storage for the Monitoring System for Biogas Production Optimization

Abstract

When monitoring for biogas production, there are many data points that are acquired throughout the process. Depending on what kind of data is acquired when processing biogas, that data can be useful for further researching biogas production. Which is why it is imperative for the data to be stored safely. The authors propose a solution for storing such data by utilizing both local and online storage. The system has several subsystems, including data transmission, data storage, and power management. The system will use a real-time clock for timekeeping, the Internet for transmitting data with the Message Queuing Telemetry Transport (MQTT) protocol, both a microSD card and a cloud database for storing the data, and a power supply system that has an automatic switching capability between the main power source and a backup power source, in case of an unexpected event such as a blackout. The cloud database will be available through the Amazon Web Services (AWS) cloud service. The implementation has been carried out by testing each subsystem and it produces satisfactory results, with the data being able to be sent regularly every hour to both the microSD card and the cloud database. The backup power source can last for 9 hours and the system is able to keep running with it.
