The paper presents a prototype of a mobile monitoring system for measuring the levels of the main traffic air pollutants (C(6)H(6), NO(2), NO(x), CO, and CO(2),) in cities. The novelty of the proposed system lies in the fact that it can be utilized to monitor emissions from urban traffic along roads and areas where traditional monitoring stations cannot be placed. In the proposed system, the monitoring device can be mounted on any moving vehicle (such as a car, bus, or truck) rather than be attached to a dedicated van, as most systems of this kind found in literature are. Analyzers used in this system are small portable structures that contain an electronic instrument to measure, record, and transmit relevant data on concentrations of the pollutants to a website. The model outcome for carbon monoxide obtained in functional tests in real conditions is also presented here. Data on temporal changes of carbon monoxide concentration are compared against meteorological parameters and speed of the vehicle. Spatial interpolation techniques are applied to obtain a nonplanar visualization of carbon monoxide and benzene concentrations in the main arteries of a city.

“…Generally, the use of these techniques requires specialized laboratories and high operating costs. A summary of nonstationary monitors that use these technics and that are currently used in industry is presented in Wardencki [2]. However, these monitors, despite being transportable, are characterized as being bulky, heavy, and expensive and will not have the ability to make measurements in motion.…”

Today, the environmental monitoring and quality have a growing interest. This promotes the development of new monitoring tools, and especially those with outstanding reliability and response time, and nonstationary features. This paper presents the design and implementation of a transportable gas detection and environmental monitoring device. Ideas taken from the Arduino and Lego constructions are kept in mind during the design of the device, looking further facilitate the development of product family of this device; likewise, the use of reconfigurable and interconnectable platforms with open hardware are considered. The transducers have been selected based on their reliability, small size and easy inclusion in an electronic system. Then, was developed a device that supports transducers for environmental gases, such as: carbon monoxide (CO), ozone (O 3 ), volatile organic compounds (VOC), nitrogen dioxide (NO 2 ) and sulfur dioxide (SO 2 ); as well as the possibility to interface with other systems for common gases such as carbon dioxide (CO 2 ) and oxygen (O 2 ) before developed. Other environmental measures such as speed and wind direction, temperature and relative humidity, may also be included. In this case, a configurable platform based on mixed-signal circuits, PSoC5, was used for the development of embedded system. This platform can be interfaced with different Arduino shields and achieves the integration of several analog functions. This system manages, acquires and processes signals from the above transducers. The measurements can be displayed on an LCD display, save into an SD memory and send to the Web using Ethernet interface. The device is hand size, easy to carry and can operate with a battery. Its user interface is simple and provides updated and in-situ readings. Currently, successful results have been obtained from the functional and metrology testing of the manufactured prototype.

“…Some research has found negative health effects from prolonged exposure to various gases and particles in schools, which makes it necessary to control and monitor them [1]. Stationary analytical devices used in the routine quality analysis of atmospheric air are expensive and complex to transport and install on site [2]. As an alternative, portable analysers exist to detect and identify specific compounds or groups of compounds present in the air, both indoors and outdoors [3][4][5][6].…”

A portable device based on a colorimetric sensor to determine the atmospheric level of CO 2 gas is presented in this work. The system is based on a low-cost, low-power System on a Chip (SoC) microcontroller with integrated Wi-Fi. A user-friendly application was developed to monitor and log the CO 2 measurements when the system is connected to a Wi-Fi network. The sensing membrane is directly deposited on the surface of the colour detector, thus reducing the complexity of the system. This sensing membrane is formed by a pH indicator α-naphtholphthalein, tetramethylammonium hydroxide pentahydrate, 1-ethyl-3-methylimidazolium tetrafluoroborate, Tween 20 and hydroxypropyl methylcellulose as the hydrophilic polymer. The system has been fully characterized, obtaining response and recovery times of 1.3 and 2.5 s, respectively, a limit of detection of 51 ppm, and an average resolution of 6.3 ppm. This portable device was applied for the in-situ determination of CO 2 gas in the atmosphere inside classrooms in several secondary schools. The measurements were taken during complete workdays and the results were statistically compared with the same measurements taken using a commercially available non-dispersive infra-red (NDIR) device. No significant statistical differences were found between the results obtained using both devices. A complete statistical treatment of the measurements made with the proposed portable device was carried out. The obtained results show that the *Revised Manuscript (clean copy) Click here to view linked References 2 concentration of CO gas in some schools was higher than the desired concentration, with regard to influencing the student's health, safety, productivity and comfort. This demonstrates the need to control this parameter to ensure appropriate indoor environmental quality (IEQ).
