Sistema Embarcado de Monitoramento e Alerta de Temperatura para Data Center

Abstract

Data Centers are fundamental to the information technology infrastructure, ensuring the storage, processing, and distribution of data. Ensuring adequate thermal conditions in these locations is essential for the performance and operation of the equipment, requiring precise monitoring and efficient operation of the cooling system. Within this context, this paper presents an on-site Thermal Monitoring and Alert System (SMAT, acronym in Portuguese) and via WhatsApp for Data Centers. The system was developed using the ESP32 microcontroller in conjunction with a thermistor sensor and other components. Among the SMAT functionalities, the sending of notifications via WhatsApp and the possibility of remote code updates, when necessary, through the Over the Air (OTA) protocol stand out. Thus, SMAT presents itself as an effective tool for temperature monitoring in Data Centers, helping to avoid additional operating costs resulting from high temperatures or excessive cooling, in addition to contributing to the increase in the useful life of the equipment. The system also helps to promote energy efficiency by monitoring the actual need for cooling. In order to verify the functioning and usability of SMAT, tests were carried out in a real Data Center of an Energy Efficiency Center, which demonstrated that the module operated correctly and as expected, in a scenario considered to be of high temperature. In view of this, the authors conclude that SMAT is a functional tool for monitoring Data Centers, due to its capacity for precise sensing, information storage and remote calibration.
