In this work, we demonstrate the alpha prototype for a wearable air quality sensor system. This system will be used to create precise, high-resolution maps of the environment to help individuals with respiratory disease track their response to pollutants, determine when to pre-medicate, or avoid areas with poor air quality altogether. The data from such a map will provide improved accuracy over the...
In this paper, an online working condition monitoring system is designed to early warn environmental quality in manufacturing industry. It is very crucial to provide real time and accurate data for staffs, stakeholders and control center to monitor factory air quality at working place. By uploading the all collected data on internet, the environmental condition can be monitored in real time by users...
This work aims to present the results of the first phase of crowdfunding campaign devised to involve general public in the development of a portable device for air quality monitoring and the associated infrastructure. A portable device based on an array of electrochemical sensors has been developed and calibrated in lab in order to build detailed maps of personal exposure to air pollutants with the...
The significant decrease in agricultural land and the rapid development of hydroponic system technology such as Nutrient Film Technique (NFT), have brought huge challenge to farmers. This hydroponic system requires special attention to several parameters such as the water temperature, water level, acidity (pH), and the concentration of the nutrient (EC/PPM). We first monitor and collect information...
The coordination of resources offered by multiple cloud providers to the end users aims to improve the Quality of Service. However, such systems exhibit a higher complexity and heterogeneity, which need to be handled correctly. In a large network of sensors provided by an Intercloud, the role of the monitoring processes is to identify existing issues and further report them for reconfiguration. Faulty...
Context awareness plays an important role that is implemented in smart application. It increases the productivity of smart home as well as pervasive and mobile application. For improving the performance of monitoring human activity that leads us to solve the problem and in order to reduce energy use in case the user forgets to turn off the light, or if we have to take time to walk to the installation...
This paper investigates a real-time water quality monitoring system by using a proposed brokerless publisher-subscriber (pub/sub) architecture framework. On the system, sensors sense the water measurement metrics, including temperature, pH, and dissolved oxygen level. All collected data are stored in a database and computed stochastically for further analysis on water quality. A complementary experiment...
The world of medical science is an emerging area that has accelerated with new technologies and this is the time when the vision of “The internet of things (IoT)” has turned into reality. IoT can play a significant role in healthcare domain by managing chronic diseases at one end as well as preventing diseases on the other hand. People demand more care at reduced clinical costs, remote health monitoring...
From the second half of the 1990s, thanks to more affordable and more powerful technology and systems for recording based on miniaturized sensors, we can observe a more intensive development of a system that monitors the physical and psychological conditions of soldiers. Systems for measuring of physical and medical data for the diagnostics of physical and psychological state has significantly spread...
Heating, ventilation, and air conditioning (HVAC) systems can consume a large percentage of the energy used in a typical building. Intelligent building automation systems (BAS) are widely deployed to enable more efficient HVAC utilization, thus reducing the energy consumed. Enhanced data requires distributed sensing. We propose an instrumentation system for a low-cost, over-the-top efficiency monitor...
Nuisance from gaseous emissions is evaluated depending on their nature: For known pollutants, analytical instruments provide reliable technical measurements; odors, however, have to be assessed through human sensory analysis. For impact sites, complexity is increased by the size of the relevant area and the scarcity of occurrence. Sensor systems could supplement regulated procedures with continuous...
A fiber-optic multi-stress monitoring system which uses 4 FBG sensors and a fiber-optic mandrel acoustic emission sensor is proposed. FBG sensors and a mandrel sensor measure different types of stresses occurring in electrical power transformer, such as temperature and acoustic signals. The sensor system uses single broadband light source to address the outputs of both sensors using single fiber-optic...
In hydraulic piping system, health management has become a challenging task. As operating in harsh environment, damage detection and fault diagnosis are important to hydraulic pipes. In this paper, an intelligent monitoring system is proposed for hydraulic pipes based on multiple sensors. Firstly, it collects and records various parameters of pipes such as vibration, hydraulic pressure, temperature,...
In healthcare, effective monitoring of patients plays a key role in detecting health deterioration early enough. Many signs of deterioration exist as early as 24 hours prior having a serious impact on the health of a person. As hospitalization times have to be minimized, in-home or remote early warning systems can fill the gap by allowing in-home care while having the potentially problematic conditions...
The strategic infrastructure, electrical grid, railroad, water and natural gas delivery grids are nowadays the target of choice for either terrorist or stealing activities. Monitoring the strategic infrastructure in order to prevent failures due to such activities is not an easy task due to the complexity of these systems. In this article it is presented a possible solution for monitoring the 110/400...
Going home will take on a new meaning and inviting with the increasing prevalence of IoT sensors being incorporated into the modern household. A smart home is comprised of IoT sensors, IoT actuators and a computational system thinking machine for communication, computation, control and visualizations (in-house and remote), which work together to benefit the homeowner in multiple ways. Three of the...
This paper presents a novel simplified cost effective binary based mechanism for eliminating problems in existing condition monitoring and diagnostic techniques. The existing techniques are engraved with problems like high cost of their implementation, failure to detect multiplicity of faults, complicated diagnosis system, expert knowledge, inherent ambiguities etc. The mechanism developed in this...
We have developing a wireless sensor network system for water quality monitoring. It consists of various sensors for the sensing of physical and chemical properties of water, and systems including wireless communication module, power module and interface between sensors and wireless communication module. In this paper, we report the development results of a novel wireless sensor network platform for...
Internet of things (IoT) has become a new trend after Internet in Information Technology. Traditional Home Automation techniques and Wireless Home automation with the aid of internet of things (IoT) are gradually gaining popularity. The main challenges with these systems are security and user friendliness. In this paper we propose a system based on the secure authentication systems of social networking...
Falls are the leading threats of death, injury and hospital admissions of seniors. About one third of seniors fall every year. Real time fall detection is thus critical to support independent livings of seniors by getting timely interventions from carers/family members. Recent years along with the IoT booming, many wearable sensor based fall detection systems have been developed. However privacy concerns...
