Design enhancements of the smart sediment particle for riverbed transport monitoring

This paper discusses new enhancements that are being made to the existing ‘Smart Sediment Particle’. The smart sediment particle has been designed and implemented to track its own 3-dimensional trajectory when placed in a riverbed. This device serves as a tool to detect sedimentation in rivers. The device has been developed over the years, with its size diminishing significantly down to a sphere of 2cm radius. The readings obtained from the pebble are accurate and match well with other independent motion sensor readings. Currently a novel IPT (Inductive Power Transfer) based power supply is being integrated to this device, to charge it wirelessly, when it has been extracted from the water. A new low power, miniaturized microcontroller has been introduced to minimize the power consumption and the PCB real estate of the device. The paper discusses these new enhancements in detail and also other potential enhancements such as error compensation and wireless data transfer

An energy-efficient internet of things (IoT) architecture for preventive conservation of cultural heritage

[EN] Internet of Things (IoT) technologies can facilitate the preventive conservation of cultural heritage (CH) by enabling the management of data collected from electronic sensors. This work presents an IoT architecture for this purpose. Firstly, we discuss the requirements from the artwork standpoint, data acquisition, cloud processing and data visualization to the end user. The results presented in this work focuses on the most critical aspect of the architecture, which are the sensor nodes. We designed a solution based on LoRa and Sigfox technologies to produce the minimum impact in the artwork, achieving a lifespan of more than 10 years. The solution will be capable of scaling the processing and storage resources, deployed either in a public or on-premise cloud, embedding complex predictive models. This combination of technologies can cope with different types of cultural heritage environments.This work was partially funded by the Generalitat Valenciana project AICO/2016/058 and by the Plan Nacional de I+D, Comision Interministerial de Ciencia y TecnologiA (FEDER-CICYT) under the project HAR2013-47895-C2-1-P.Perles Ivars, A.; Pérez Marín, E.; Mercado Romero, R.; Segrelles Quilis, JD.; Blanquer Espert, I.; Zarzo Castelló, M.; García Diego, FJ.

Performance of Residential Heating and Cooling Control Strategies using Distributed Wireless Sensor Networks

Previous work has suggested that residential space heating and cooling control strategies that partition the structure into individual zones using wireless sensor networks might result in lower energy consumption compared to systems using a single-sensor thermostat. Questions have been posed as to whether these strategies can achieve the same level of performance in a variety of geographic locations and climates. This study compared four control strategies that utilized a wireless temperature and humidity sensor network to regulate the comfort of a residence in the mid-Atlantic region of the United States during the summer and winter. In particular, the energy consumption and comfort levels of each multi-sensor strategy were compared to a baseline strategy that mimicked a single thermostat. The difference in energy usage measured by each control strategy was found to be statistically insignificant. However, experiments indicated that these strategies may nevertheless result in improvements in thermal comfort
