Smart inventário: implicações do uso de sensores bluetooth low energy na melhoria da eficiência do inventário patrimonial na Administração Pública Federal

Abstract

This study proposes an improvement in asset inventory management at a federal public educational institution through the use of Bluetooth Low Energy (BLE) sensors for asset tracking and identification. The methodology adopted was action research, carried out as a proof of concept with the researcher as the sole participant, responsible for all stages of data collection and analysis. Data were generated from the interaction between the sensors, the scanning application, and a mobile device. The study assessed the technology’s impact on process efficiency, reduction of physical effort, and the time required to complete the inventory. The results indicate that the use of sensors made the procedure faster, less physically demanding, more organized, and smoother. However, the economic analysis based on return on investment (ROI) shows that, despite the time savings, the initial investment cannot be recovered within a single cycle, requiring reuse of the devices across multiple inventories to approach economic feasibility.
