Abstract: The increasing quantity of CO2 is a big problem leading to global warming. Therefore it is necessary to properly design a system to monitor the amount of CO2 in the atmosphere to prevent the debacles of future.This paper gives us details about how to develop CO2 monitoring system based on the ZigBee protocol. Graphical user interface is helpful to display monitoring data on screen. This is another important advantage present in this paper.
