The problem with monitoring plant health is that they either need time-consuming laboratory analyses or costly monitoring equipment. This undertaking seeks to develop an affordable, real-time method for assessing plant well-being. The objective was to construct a "Mood Ring" for plants, employing Plant Microbial Fuel Cell (PMFC) technology as a bio-electrical monitoring device. The methodology involves the following steps. Electrons released by bacteria during the decomposition of sugars exuded by plant roots were harvested using simple metal electrodes inserted into the soil. Throughout the experiment, Open-Circuit Voltage was monitored in response to environmental fluctuations, such as variations in water levels. Time-series plots were employed to analyze the data, thereby facilitating the identification of a correlation between electrical power and plant vitality. A key innovation of this approach is using living organisms as sensors, which allows for the collection of environmental data without any cost. The study showed that "healthy" plants, those with good irrigation, produced strong electrical signals. In contrast, "unhealthy" plants, which were stressed, showed a noticeable decrease in signal strength. This research effectively demonstrates the potential of soil electricity as a sustainable and cost-effective way to assess environmental conditions. This research is important because it could lead to better farming methods and more effective management of water resources. This great concept contributes to the more efficient utilization of resources and a deeper understanding of natural processes by providing accessible methods for determining plant requirements, even for individuals such as home gardeners or small-scale farmers.
