In this paper we present a novel approach for monitoring elderly people living alone and independently in their own homes. The proposed system is able to detect behavioral deviations of the routine indoor activities on the basis of a generic indoor localization system and a swarm intelligence method. For this reason, an in-depth study on the error modeling of state-of-the-art indoor localizatio...

This article describes the design and development of a system for remote indoor 3D monitoring using an undetermined number of Microsoft® Kinect sensors. In the proposed client-server system, the Kinect cameras can be connected to different computers, addressing this way the hardware limitation of one sensor per USB controller. The reason behind this limitation is the high bandwidth needed by th...

In this paper, a wireless sensor network (WSN) is constructed to carry out certain applications. This WSN is composed of a sensor, monitor, controller, etc. It has the benefits of low cost and low power consumption. A WSN can be used in many applications in a range of different control technologies, such as temperature monitoring. ZigBee is used to test the performance of the WSN. The experimen...

Persistent monitoring of Indoor Air Quality (IAQ) within and around buildings and structures is critical to reduce risk of indoor health concerns. Specifically, IAQ issues in large integrated buildings may stem from inadequate ventilation and/or faults in the complex HVAC systems that together with control and communication systems can be considered as complex Cyber Physical Systems (CPSs). We ...

One distinctive feature of ambient assisted living-oriented systems is the ability to provide assistive services in smart environments as elderly people need in their daily life. Since time-of-flight vision technologies are increasingly investigated as monitoring solution able to outperform traditional approaches, in this work an application-driven monitoring framework based on a time-offlight ...

This paper presents key elements on which to base the design of a strategy for a particular indoor environment measurement task. Starting from a general strategy for responding to occupant complaints and conducting epidemiological and intervention studies the paper concentrates on selected key elements, with focus on air contaminants. Strategies for grouping of occupants with the purpose of exp...

Received Jan 24, 2017 Revised Mar 30, 2017 Accepted Apr 20, 2017 This paper discusses the development of an indoor monitoring system based on passive radio frequency identification (RFID) system and Raspberry Pi 3. There are two algorithms designed for this project where the first is to link the RFID module to the Raspberry Pi 3, and the other one is to send the data obtained to a database over...

Within the framework of a French project, which aims at developing a new human presence sensor, we intend to design a sensor system simulator. During the establishment of the requirements of that new sensor we raised that the mission of a global scene survey could only be performed by a collection of several systems using very diverse technologies. This article presents the development of a met...

Wireless indoor environmental monitoring (WIEM) systems are becoming an important tool in the fight to reduce carbon emissions and improve energy efficiency in the built environment. Systems which previously targeted the commercial market are quickly moving into the residential domain with promises of drastic energy reduction. The requirements of a WIEM system, however, vary from application to...

In this chapter, we review some of the previous proof-of-principle work done in this field. Examples of water, land and air monitoring experiments are examined. Four case studies are then presented. The first three demonstrate the ability of the e-nose to classify odors from animal confinement facilities (odor source determination, odorant threshold detection, and odor abatement evaluation). Th...
