Development of wireless sensor network for monitoring global warming

This paper presents the development of wireless sensor monitoring system for environmental applications. The system is based on wireless ZigBee technology and uses 32-Bit Arduino Uno microcontroller for monitoring of environmental parameters measurements online such as carbon dioxide, oxygen, temperature and humidity levels. The CO₂, O₂, humidity, and temperature sensors are integrated into the data acquisition system. Data was collected at a certain location at Universiti Sains Malaysia, consistency models are define for analyzing the quality of data and the level of carbon dioxide and oxygen in the deployed environment. The results show that the system is capable of monitoring and analysis of CO₂ and O₂ in the deployed environment and this success shows the potential of this system for application in environment where reliable gas monitoring is crucial.
