CO2 sensing wireless sensor network- Increasing CO2 concentration in atmosphere is one of the major cause of global warming. increased soil respiration in recent years is considered a major source. Suggested sources for increase in soil respiration are microbes (due to increase in temperature) and plant roots. The need is to come up with a hardware which can do soil and atmospheric CO2 measurement with low power consumption and transmit the data over wireless to a personal computer (PC). We are in the process of designing such a system.
