This research aims to design prototype instruments to measure the black smoke on the street with a small, portable, and can compare the performance of the underlying instruments to measure the smoke black portable measuring instruments with black smoke, the paper filter by system design, the black smoke.By measuring the intensity of circuit 5 light levels to 1 watt LED bulbs to illuminate the phankradat filter, beam and use the photo diode is a light sensor. Output light intensity value is 5 levels and light levels over 5 mm LED lamp for checking the performance of the underlying instruments measuring black smoke, portable size. All of the vehicles from the research found that 91 vehicles vehicles with 1 level of tolerance is the amount of 15 vehicles accounted for 16.48 percent, and vehicles without bias. With a total of 76 cars 83.52 percent which is a high level of accuracy, so it showed black smoke, portable meter can measure levels of black smoke nearby. There is also a very fast over the use of the black smoke measuring system of filter paper black portable smoke meter can guide the development of efficient machines. Use the more versatile because have low production costs and easier to find, so it's a good template for developing, producing, black smoke in the next future.
