PSLer: A Power Supply and Data Logging Application for Microbial Electrolysis Systems

PSLer is designed to utilize commercial boards and open-source code to deliver and capture voltage in microbial electrolysis systems. This applied voltage enhances microbial metabolic processes, allowing the microbial cells to generate electrical power, which the device captures and records. Effective operation, optimization, and troubleshooting of microbial electrolysis cells rely on power suppliers and multimeters with data acquisition capabilities to ensure dependable performance and efficient resource use. In this context, the manuscript describes the development of an automatic monitoring device that incorporates a Power Supply Unit, Arduino UNO, and ADS1256 boards, with an assembly cost less than $300 American dollars. This cost-effective solution empowers researchers with limited budgets to conduct dependable and efficient research. Additionally, the manuscript provides detailed instructions for assembling and using the monitoring device. This innovative prototype overcomes the limitations of costly and inflexible commercial devices and fosters interdisciplinary research, ultimately saving time and reducing costs.
