PROJECT TITLE :
Design and Application of a VOC-Monitoring System Based on a ZigBee Wireless Sensor Network
Monitoring volatile organic compound (VOC) pollution levels in indoor environments is of nice importance for the health and comfort of people, particularly considering that people currently pay >80percent of their time indoors. The primary aim of this paper is to design a low-power ZigBee sensor network and internode knowledge reception management framework to use in the important-time acquisition and communication of data concerning air pollutant levels from VOCs. The network consists of end device sensors with photoionization detectors, routers that propagate the network over long distances, and a coordinator that communicates with a laptop. The planning is predicated on the ATmega16 microcontroller and the Atmel RF230 ZigBee module, that are used to effectively process communication knowledge with low power consumption. Priority is given to power consumption and sensing potency, which are achieved by incorporating various smart tasking and power management protocols. The measured data are displayed on a laptop monitor through a graphical user interface. The preliminary experimental results demonstrate that the wireless sensor network system will monitor VOC concentrations with a high level of accuracy and is therefore suitable for automated environmental monitoring. Each good indoor air quality and energy conservation will be achieved by integrating the VOC monitoring system proposed during this paper with the residential integrated ventilation controller.
