Abstract
Pencemaran udara dewasa ini semakin memprihatinkan. Hal ini terlihat dimana terjadi perubahan cuaca dan iklim lingkungan yang mempengaruhi suhu bumi dan berbagai pengaruh lain. Gangguan kesehatan dan ancaman kepunahan beberapa spesies makhluk hidup di bumi menjadi fenomena yang tak terhindarkan. Hal ini merupakan permasalahan global yang harus diperhatikan, karena akan berakibat sangat buruk bagi aktivitas kehidupan. Untuk mengetahui besar PPM NOx yang tercemar di perkotaan maka penelitian ini dilakukan perancangan sistem monitoring konsentrasi gas nitrogen oksida ( NOx ) sebagai emisi gas buang menggunakan sensor gas MQ - 135 berbasis mikrokontroller STM32F4 discovery, dan akan ditampilkan pada LCD 16 x 4. Berdasarkan hasil pengujian, bahwa pada pengukuran alat diperoleh nilai 95% hasil pengukuran (x) didapatkan 0,14 ± 0,3 ppm.

Air pollution today is increasingly alarming. This is seen where there is a change of weather and climate environment that affect the temperature of the earth and various other influences. Health problems and threats of extinction of some species of living things on earth became an inevitable phenomenon. This is a global issue that must be considered, because it will be very bad for life activities. To find out the amount of PPM NOx contaminated in urban area, this research is done by designing monitoring system of nitrogen oxide gas concentration (NOx) as exhaust emission using MQ-135 gas sensor based on microcontroller STM32F4 discovery, and will be displayed on LCD 16 x 4. Based on test result , That on the measurement tool obtained value 95% measurement results (x) obtained 0.14 ± 0.3 ppm.
