摘要：t.is paper present. a new wireless syst.m for t.e measurement.of CO2 gas concent.at.on for indoor and out.oor purposes based on low cost.Non Dispersive Infrared sensors. t.e syst.m has been implement.d on a print.d circuit.board in order t. obt.in different.aspect. of t.e air pollut.on. Some experiment. were achieved t. evaluat. t.e t.t.l syst.m combined wit. an android applicat.on on a smart.hone. Different.t.st. were realized in a closed room nearly filled wit. st.dent. and also direct.y while driving on t.e road. Good result. were obt.ined allowing a fut.re use for air pollut.on mapping using numerous amount. of sensors inside vehicles.
