Design of Air Pollution Monitoring System Using ZigBee Networks for Ubiquitous-City

Abstract

The innovative Ubiquitous-City was born through convergence of construction, home applications and culture, with development of up to date information technologies and ubiquitous IT. The U-City can be applied to a variety of special situations for managing functions of each city efficiently. This paper focuses on implementation of air pollution monitoring system. First, each sensor was tested after survey about market trends of a variety of sensors for detecting air pollution. Second, wireless communication modules for monitoring system were developed using wireless sensor networks technologies based on ZigBee. And then a performance of modules was estimated in the real-fields. Through software programs written in nesC for efficient routing in wireless networks were simulated using TOSSIM simulator. Finally, integrated wireless sensor board which employs dust, CO2, temperature /humidity sensor and a ZigBee module was developed. The board is embedded device based on AT91SAM7S64 porting uCOS. This paper accelerates the digital convergence age through continual research and development of technologies related the U-City.

Climate: Environmental Monitoring Using Wireless Sensor Network System

“…Authors matched the two models concerning implementation time and recommended the second flow-based design. Kwon et al (2007) developed an air pollution monitoring system coupled with dust, temperature-relative humidity and CO 2 sensors based on ZigBee platform for the ubiquitous city. In the proposed method, TOSSIM simulator was used for analyzing three kinds of routing protocols based on ARM7 architecture.…”

The Management of Indoor Thermal Comfort with Wireless Sensor Networks

“…Wireless sensor networks (WSNs) provide many advantages in terms of different properties such as data range, transmission speed, reliability, cost, and expansion compared to wired networks. In recent years, WSN, which have been used in many fields such as health, 19 remote monitoring and control, 20,21 and security, 22 have also been intensely preferred in home automation systems. In the literature, the use of thermal comfort in home automation systems, in which space heating is controlled via WSN, includes differences.…”
