Particulate matter as the one of pollutant which have complicated mixture from various organics and non organics compound with very small in diameter, start from 1 micron up to 500 micron floating on theair, so it could be more dangerous than other pollutant. One of method to detect these particullate matter is using optical sensor. The lightbeam passes in front if the sensor but not fall to it. When something passtrough these beam, the light would scattered to any directions. Some ofthese scattered light could fall and received by sensor. The lower output of the sensor shows there are much particles on the air. This final project using photointerupter MOCP70 series from FAIRCHILD semiconductor contains photodarlington and IR led then built to form 20° from the center pointof its beam. Then put on the light impermeable box. The air flowspushed by heater at the top of the box with temperature could reachmore than 70°C. The test with either white or black smoke give thesimilar result as the sensor could detect it.
