This news has came up from the scientist from University of Southampton that has recently partnership with JAIST  that is Japan Advanced Institute of Science and technology. Under this they have developed a graphene based sensor that will be detecting on the low concentration of air pollution at comparatively low power consumption.

Electrical resistance of the graphene will be observing and discipline the process of individual seo2 molecule along the graphene as quantised change in the resistance . According to the team, CO2 with a concentration of 30parts per billion was detected within a few minutes.
