The document discusses the development of an air pollution monitoring system using wireless sensor networks and ZigBee technology to measure temperature, humidity, and CO2 levels for applications in an Ubiquitous City. Sensors were tested and wireless communication modules using ZigBee were developed to efficiently route data. An integrated wireless sensor board was created combining the sensors and a ZigBee module to monitor air pollution remotely.

1. Temperature and 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.

2. 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 C for efficient routing in wireless networks.
Finally, integrated wireless sensor board which employs CO2, temperature
/humidity sensor and a ZigBee module was developed.
This paper accelerates the digital convergence age through continual
research and development of technologies related the U-City
