Indoor Air-Quality Data-Monitoring System: Long-Term Monitoring Benefits

Abstract

Indoor air pollution has been ranked among the top five environmental risks to public health. Indoor Air Quality (IAQ) is proven to have significant impacts on people’s comfort, health, and performance. Through a systematic literature review in the area of IAQ, two gaps have been identified by this study: short-term monitoring bias and IAQ data-monitoring solution challenges. The study addresses those gaps by proposing an Internet of Things (IoT) and Distributed Ledger Technologies (DLT)-based IAQ data-monitoring system. The developed data-monitoring solution allows for the possibility of low-cost, long-term, real-time, and summarized IAQ information benefiting all stakeholders contributing to define a rich context for Industry 4.0. The solution helps the penetration of Industrial Internet of Things (IIoT)-based monitoring strategies in the specific case of Occupational Safety Health (OSH). The study discussed the corresponding benefits OSH regulation, IAQ managerial, and transparency perspectives based on two case studies conducted in Spain.

Digitalization: An Opportunity for Contributing to Sustainability From Knowledge Creation

“…The selected approach is to discuss the effects of digitalization by focusing on its drivers, like the implementation of Industry 4.0, mainly oriented not only on production but also on the health of workers and environmental working conditions. This is relevant as several authors [36,37] have highlighted that technologies driving Industry 4.0 are in many cases developed in silos and manufacturers'initiatives are isolated and fragmented, therefore dangers will multiply and the net impact on OHS will be negative.…”

“…In order for an organization to step into the digital world, it is not just a matter of digitizing its working methods, products or services, but also strategies and business models need to be reviewed accordingly [43]. The Industry 4.0 paradigm, also including IIoT [44], IoT [37], RFID and several other drivers contributes to increasing their innovation and competitiveness.…”

Indoor Air Quality Improvement by Simple Ventilated Practice and Sansevieria Trifasciata

“…shows that the greatest variation in RH was apparent for the minimum values during September and October 2017, because of the influence of outdoor air that is caused by various groups visiting the office at that time. Reducing the RH by introducing ambient air is only practicable while taking that the RH value can vary diurnally or hourly into consideration.The room T was maintained close to the comfortable standard (23 to 26 °C)[39], consistent with the preferred environmental conditions for Thailand established in the thermal comfort survey(26 …”

“…IAQ has been an important issue in Europe and America since the 18th century [4]. However, there has been relatively limited research on the topic in Association of South East Asean Naitons (ASEAN) countries [15,25] and few long-term studies have been conducted [26]. The main aim of this research was to improve the IAQ of an air-conditioned office in Thailand with a poor ventilation system by practicing simple ventilation operations and locating the mother-in-law's tongue plants in the office, with the second aim of achieving lower energy consumption.…”

GASDUINO-Wireless Air Quality Monitoring System Using Internet of Things

“…The IoT technology can be easily integrated with artificial intelligence, embedded systems, and mobile applications to monitor and analyze big data of the air quality index measurements in the developed framework of smart cities and also in smart homes [7]. Furthermore, the IoT application to air quality monitoring demonstrated the possible benefits of long-term, cost-effective solution, real-time capabilities, and reporting the air quality index (AQI) information to contribute for the concept definition of Industry 4.0 [8,9]. Moreover, security and privacy techniques [10] can be implied in the proposed IoT systems to provide restrictions on the AQI information access for all stakeholders and industrial organizations [11].…”
