Low-Cost System for Monitoring Water Quality Parameters in Lentic and Lotic Eco...
Benguela, S.; Caetano, F.; Silveira, C.Water consumption is vital for human survival and plays a crucial role in the healthy functioning of the human body. However, the use of drinking water for human consumption has raised growing concerns due to water scarcity and droughts. Therefore, it is necessary to implement projects aimed at the effective use of water, including waste reduction and the reuse of alternative sources. This paper aims to describ...
AirVA - Indoor Air Quality Monitoring and Control with Occupants Alerting System
Ramos, A.; Bom Jesus, V.; Gonçalves, C.; Caetano, F.; Silveira, C.The objective of this work is to detail the development of an IoT system to monitor the indoor air quality index and record the entry and exit of occupants of the same space. Data is collected, processed, and sent to a data server through the MQTT communication protocol. This server is responsible for storing and displaying information on the ThingsBoard platform. To evaluate the solution, the air quality index...
PetWatcher – Ubiquitous Device Proximity Location System
Fernandim, L.; Gonçalves, C.; Caetano, F.; Silveira, C.This paper presents a solution, PetWatcher, that uses BLE technology in conjunction with the Blynk IoT platform to monitor the proximity of specific devices to a landmark. The main objective is to monitor the presence of devices placed on animals, through MAC address, in relation to a fixed point, controlling the movement of the devices in a specific area. The system was developed using the ESP32 microcontrolle...
EgiCool - IoT Solution for Datacenter Environmental Control and Energy Consumpt...
Gonçalves, V.; Daniel, J.; Gonçalves, C.; Caetano, F.; Silveira, C.The increasing demand for digital services and cloud computing has brought the problem of energy consumption of datacenters and the quest for innovative solutions. Among the emerging approaches, free cooling stands out as a promising technique that allows a significant advancement in the operational efficiency of datacenters, contributing to environmental sustainability. The objective of this work is to detail ...
Sustainable and Autonomous Soil Irrigation: Agro Smart Solution
Santos, G.; Vicente, G.; Salvado, T.; Gonçalves, C.; Caetano, F.; Silveira, C.Water scarcity is probably one of the most serious problems that humanity will have to face globally. For that reason, it will certainly be urgent to try to define practices and find solutions that, in a first phase, allow to mitigate the problem, but whose ultimate objective will be to overcome the situation. This chapter presents an irrigation system set on an internet of things platform, able to act in real ...
Monitoring Indoor Air Quality and Occupancy with an IoT System: Evaluation in a...
Ramos, A.; Jesus, V.; Gonçalves, C.; Caetano, F.; Silveira, C.Indoor air quality is a determining factor in maintaining occupant comfort, especially in educational environments such as classrooms. Traditional methods of monitoring indoor air quality and occupancy, such as casual inspections or periodic measurements, do not provide timely and accurate information for those who must make decisions about ventilation and controlling the number of occupants. Internet of Things...
