Design of the emission measuring equipment of air pollution index based on real time

Abstract

Abstract This study aims to design a prototype of portable measuring instrument to measure the emission concentration of air pollution index and to easily access data from the portable measuring devices in real time. The model of this tool is compact using five sensors. The operating system of the sensor started from the power supply giving each voltage of 5 volts to the microcontroller, the sensor reads the concentration value of emissions in the air and the analogue data processed by a microcontroller converted into digital data. Microcontroller dispatch to digital data as output displayed on SD Card, TV, and LCD displays. The results of this study is the prototype of a practical emission measuring portable device with a small dimensions of 8 cm × 15 cm and low power usage. The emission concentrations displayed are PM10, SO 2 , CO, O 3 , and NO 2 via internet-based smartphones or laptops in real time.
