Abstract
The development and implementation of low-cost sensors, in combination with microcontroller systems such as Raspberry
Pi, Arduino, and ESP32, have opened new avenues in the field of geosciences, providing accessible and flexible solutions for the
monitoring and analysis of natural phenomena. These platforms allow for the creation of adaptable and customizable monitoring systems capable of recording various environmental parameters, such as temperature, pressure, humidity, and geomagnetic field variations. This article examines the application of these technologies in geosciences, with a particular focus on their advantages and potential uses, primarily emphasizing their low cost and versatility. These features in scientific instrumentation can democratize access to research and promote science-oriented education. Through a case study on the detection of geomagnetic storms using an ESP32 and an HMC5883L magnetometer, the article presents a step-by-step tutorial on how to set up an efficient and affordable monitoring system, with the aim of showcasing its practical applications in both academic and community-based projects. The case study underscores the potential of these tools for conducting preliminary research in resource-constrained environments or as an introduction to more advanced concepts in geosciences.
Although low-cost sensors may be limited in precision compared to high-end equipment used in specialized laboratories, they offer significant opportunities for exploratory research, educational initiatives, and the expansion of monitoring networks in areas with limited technological infrastructure. Their ease of integration and programming, coupled with the abundance of available documentation, make these technologies highly suitable for scientists, educators, and students, providing access to tools that would otherwise be unattainable. In this way, these systems represent a valuable contribution to the advancement of geological sciences and their broader dissemination to diverse sectors of society.
