Desenvolvimento de um sistema embarcado de baixo custo para agricultura de precisão

Abstract

Precision agriculture plays a crucial role in increasing efficiency and productivity in crop production by monitoring environmental variables such as air humidity, temperature, atmospheric pressure, ambient light, soil moisture and pH, carbon dioxide (CO2), and volatile organic compounds (VOCs). With the advancement of the Internet of Things (IoT) and the reduction in costs of Wi-Fi modules, these technologies have become more accessible, enabling the integration of embedded systems and Wi-Fi connectivity for real-time transmission of collected data, facilitating agile and informed decision-making. In this context, the objective of this work is to develop a low-cost Printed Circuit Board (PCB) with a low-power microcontroller and precise sensors to collect relevant data for agriculture and environmental variables. The project also aims to be sustainable, utilizing solar energy as a power source and employing a rechargeable battery to minimize environmental impacts. Therefore, the proposal is to make these technologies accessible not only to large-scale producers but also to small-scale farmers with limited resources for investing in advanced solutions.
