“…Techniques for reducing energy consumption in the sensor node were also described in [32]. Energy consumption also was the main focus in [34], the proposed environment monitoring system (EMS) consisted of a GPS module and a WSN for remote location monitoring for AQ. In 2004, Yan et al presented a strategic approach for energy reduction in designing and implementing a WSNs [72].…”

“…Many RF circuits have been studied and designed for global navigation satellite systems [1,2,3,4,5,6,7,8]. As the antenna plays an important role in the RF systems, many different types of antenna have been investigated and reported at 1.575 GHz including planar inverted-F antenna (PIFA) [9], U-shaped [10] and meshed [11] patch, spiral [12], substrate-integrated-waveguide [13] and monopole [14] antennas. Although satisfactory performance has been achieved based on the above designs, the antenna can only be used for wireless communications.…”

A linearly polarized slot antenna integrated with solar cells is presented. The proposed antenna operates at the center frequency of 1.575 GHz for the global navigation satellite systems. 40 solar cells are adopted for the radiation structure and 4 slots are formed by these solar cells, which can not only be used for wireless communication but also generate DC energy via the photoelectric effect. The proposed design has achieved a relative bandwidth of 19.9% from 1.45 GHz to 1.77 GHz. Bidirectional radiation performance has been realized and the measured gain at 1.575 GHz is 6.6 dBi.

Abstract-An air quality monitoring system (AQMS) based on IEEE/ISO/IEC 21451 standards is presented. In the development of AQMS, we have used the GSM wireless communication module. The developed system is capable of real-time measurement of air polluted gases such as CO 2 , CO, NO 2 , and SO 2 . The machine-to-machine communication of the air quality monitoring station and PC with the sink node was successfully implemented. Various gas sensor technologies were evaluated for the system and ultimately electrochemical and infrared sensors were used. Hardware and software for an AQMS was designed and implemented. The AQMS uses an array of sensors to take measurements of the ambient air surrounding it and wirelessly transmits the data to the base station. A graphical user interface (GUI), which makes it easy for end user(s) to interact with the system, was developed. Gas concentration values are plotted on the GUI. The defined calibration of the instruments at time interims assures that the desired accuracy is sustained. This paper offers further elucidations to design disputes raised in earlier studies.Index Terms-Air quality monitoring, GSM module, sensor array, graphical user interface, ISO/IEC/IEEE 21451standards.
