An IoT System for Monitoring and Data Collection of Residential Water End-Use Consumption

Development of an IoT System for the Generation of a Database of Residential Water End-Use Consumption Time Series

“…Starting from the authors' previous work [11], the paper represents an update of the case study realized, showing first analysis on the generated repository. The aim of the application is to test the IoT monitoring system on a starting case with one customer to understand the intrusiveness of the system during daily use, use overlap, and the limitations of the method that can be improved for the application in more complex configurations.…”

“…The design of the IoT water end-use monitoring system is made up of a flow sensor, a microcontroller, and a Content Management System (CMS), which carry out a data collection platform and integrate basic processing and visualization commands, as shown in Figure 1 [11]. The sensor YF-S201 allows for the measurement of the quantity of water passing through it, counting the electrical pulses emitted for each revolution.…”

“…To this purpose, in order to obtain a database at end-use level, an Internet of Things (IoT) water end-use monitoring system able to read real-time water end-use consumption in a residential apartment [11] was developed. The paper describes briefly the IoT solution already developed and its installation on the water fixtures of a real apartment used as a pilot site.…”

“…Finally, the paper shows the potentiality of applying disaggregation techniques on a database of real water end-use consumption in order to identify how the data of single end-use categories could be used to profile users and to analyze residential water usage. The application is still ongoing, and this paper, starting from the authors' previous work [11], represents an advance of this study with a particular focus on the relevance of disaggregated data for user profiling.…”

Impact of COVID-19 emergency on residential water end-use consumption measured with a high-resolution IoT system

“…An IoT system developed combining a flow sensor, a micro-controller, and a content management system was installed on all the fixtures in the apartment except on the toilet and dishwasher due to positional constraints. To detect water consumption from flush toilet and dishwasher, an open-source app based on HTTP hyperlinks was configured (Di Mauro et al 2019). Moreover, high-resolution data were also collected at the household level using an ultrasonic water meter based on Long-Range (LoRA) transmission.…”
