8 pagesDate: March 31, 2020


Air is important to human-being. Every day, people mostly use automobiles for traveling. Consequently, the air in the passenger room must be appropriated for the passenger and it must not endanger the health of the passenger. This research article would like to present the air quality instrument for cars, which concern the level of oxygen, carbon dioxide, and carbon monoxide as the design of this air quality instrument consists of 3 main parts. The first part is the air sensor composing of ME2-O2 oxygen sensor, SenseAir S8 carbon dioxide sensor, and MQ-7 carbon monoxide sensor. The data from sensors will be sent to Arduino Uno data processing to compare with the setting values, then the value of oxygen level, carbon dioxide level, and carbon monoxide level will be sent to the display. If the value is over the setting point, the data processing will notify with the voice signal in the passenger room so that the user would be able to fixes the problem and remain the air at the standard criteria with the percentage error for the meter. This car air quality meter is calibrated with the standard instrument. The oxygen gas value is 2.32 % error, carbon dioxide value is 1.2 % and the carbon monoxide value is 2.74 % and tested according to 4 case studies which are 1) when the car moves at a speed of 60 - 80 km/h for 1 hour 2) when the car is parked outdoors for 1 hour 3) when the car is stationed, the pollution will spread inside the cabin and 4) when the car is stationary while the engine is off is test by releasing smoke into the car.

Keyphrases: air quality instrument, carbon dioxide, carbon monoxide, oxygen
