Monitoring distribution system of carbon monoxide and surface ozone based on GPS and microcontroller

Jakarta is the most populous city in Indonesia. This is directly proportional to the increasing number of motorized vehicles in Jakarta. The number of Jakarta motorized vehicles causes air pollution in Jakarta to become uncontrollable. Air pollution is the presence of one or more physical, chemical or biological substances in the atmosphere in an amount that can endanger the health of living things. Ozone and Carbon Monoxide, including dangerous elements that exist in air pollution. Ozone is a pollutant that causes significant respiratory disease. Carbon Monoxide is dangerous because it can form compounds with Hemoglobin to form HbCO, and this is toxic to the blood. We can find out the quality of the air somewhere, through the content of Ozone and Carbon Monoxide in the area. At present the number of Ozone and Carbon Monoxide gauges in Indonesia is still small, so that not all regions have been monitored for air quality conditions. The purpose of this design is to determine the level of air quality and to monitor ozone gas and carbon monoxide automatically based on Global Positioning System (GPS) and portable. This system was built using Arduino Mega 2560 (used as a controller), ozone sensor, Carbon Monoxide gas sensor and GPS (used as a timing and determinant of location). Programming is done using the Arduino IDE application. The measurement results are stored using a microSD Card, and displayed on the LCD. This system can inform the condition of air quality in an area, because this tool is portable (can be carried anywhere), in real time and data generated every second.
