Rancang Bangun Alat Pendeteksi Polusi Udara Menggunakan SD Card

Abstract

Air pollution is an important problem that can threaten human life.Many human activities that cause air pollution. An air pollution detector has been made using an SD card. The sensors used in the design of this tool are the MQ-135 sensor as a detector which is controlled by Arduino Nano and is equipped with a display of measurement result on the LCD and the result data. Measurement are stored on SD card or memory card . The sample used in this tool is using matches and burne paper. The test result of this tool are quite satisfactory where the average percent of the measurement result are air pollution as much as 173,6 , air consentration as much as 17,2ppm, CO smoke as much as 49,6, and LPG gas as much as 2,4 .
