“…Unlike our wireless sensor, it cannot measure atmospheric pressure and battery operation is not possible. Wireless sensors are primarily intended for implementation in existing "unintelligent" buildings, especially schools which are not equipped by industry standards for building automation such as KNX [1]. That is why our environmental sensor has been designed as a wireless sensor that can be used to create an extensive wireless sensor network without any building modifications to existing buildings.…”

The article describes the development and implementation of a complex monitoring system for measuring the concentration of carbon dioxide, ambient temperature, relative humidity and atmospheric pressure. The presented system was installed at two locations. The first was in the rooms at the Department of Cybernetics and Biomedical Engineering, Faculty of Electrical Engineering and Computer Science, VŠB-Technical University of Ostrava. The second was in the classrooms of the Grammar School and Secondary School of Electrical Engineering and Computer Science in Frenštát pod Radhoštěm. The article contains a detailed description of the entire measurement network, whose basic component was a device for measuring carbon dioxide concentration, temperature and relative humidity in ambient air and atmospheric pressure via wireless data transmission using IQRF® technology. Measurements were conducted continuously for several months. The data were archived in a database. The article also describes the methods for processing the data with statistical analysis. Carbon dioxide concentration was selected for data analysis. Data were selected from at least two different rooms at each location. The processed results represent the time periods for the given carbon dioxide concentrations. The graphs display in percent how much of the time students or employees spent exposed to safe or dangerous concentrations of carbon dioxide. The collected data were used for the future improvement of air quality in the rooms.

“…For example PMS 5000/3000 is popular among hobbyists, as well as it is often employed in inexpensive measurement devices that are commercially available to wide range of public customers, and was successfully used in research attempts [11,12]. Such sensors were also deployed in Building Management Systems based on KNX network to monitor interior air quality in homes and offices [13,14]. Despite such low-cost equipment that is popular and provides satisfactory results as if compared against expensive reference methods, it is hard to find exact information about its metrological parameters and precise information about capabilities of devices employing it.…”

This paper comprehensively presents key issues in design of an original optoelectronic measurement device built to assess amount of suspended particulate matter. The paper is introduced with a short explanation of concerns with a suspended particulate matter, what role it has in the air quality and how it affects health of human population. Then, problems of construction of the measurement device supported by a theoretical explanation on the basis of Mie theory are discussed. Subsequently, it is followed by an analysis of the device operation both in laboratory and in real conditions. Results obtained with the presented device are compared with the professional measurement equipment and an expensive, outdoor measurement station. Paper is concluded with observations of differences in spatio-temporal PM change at very close but significantly different city locations.

“…In addition to these facilities, Internet of Things (IoT) [ 3 , 4 ] platforms can be developed in order to enable the interaction between people and these monitoring and control systems in a virtual environment. The monitoring and control devices used in smart homes are interconnected throughout communication networks (fieldbuses) based on standardized protocols [ 5 ], such as Building Automation and Control Networks (BACnets) [ 6 ], LonWorks [ 5 ], Modbus [ 7 ], and EIB/KNX [ 8 ]. The use of these standardized communication networks ensures interoperability between devices provided by different manufacturers.…”

The development of the smart building concept and building automation field is based on the exponential evolution of monitoring and control technologies. Residents of the smart building must interact with the monitoring and control system. A widely used method is specific applications executed on smartphones, tablets, and PCs with Bluetooth connection to the building control system. At this time, smartphones are increasingly used in everyday life for payments, reading newspapers, monitoring activity, and interacting with smart homes. The devices used to build the control system are interconnected through a specific network, one of the most widespread being the Building Automation and Control Network (BACnet) network. Here, we propose the use of the BACnet Application Layer over Bluetooth. We present a proposal of a concept and a practical implementation that can be used to test and validate the operation of the BACnet Application Layer over Bluetooth.
