A low cost approach of multisensor device for global warming studies

Global warming is an issue that keeps coming up recently with the increase of temperature and carbon dioxide level. Scientist believes that the main cause of this is because of the deforestation, pollution, carbon emission from transportation and factories that led to this global warming. However, there are also skeptics that believe otherwise. To prove the cause of global warming and whether it is an event that occurs every now and then as some skeptics and scientists suggested a multi sensor device is build, which consist of temperature, humidity, carbon dioxide and oxygen. With limited funding and a few different location to be tested to prove this phenomena, a low cost device is built so that it will be within the budget of this project as well give the result that is to determine whether development has cause the global warming and forest and absorbing the CO2 emission to keep the world cool. Thanks to open source hardware, the sensor system can be build economically.
