A Study on the Improvement of the Accuracy of Low-Cost Light Scattering Method Particulate Matter Sensors
This study is aimed to verify the validity of developed devices and sensing data by measuring particulate matter (PM10, PM2.5) using the low-cost light scattering type particulate matter (PM) sensor and comparing and analyzing the measured data with the domestic standard PM measurement data. We have developed a system that enables users to control the device through mobile service and check the state of PM and solved the accuracy problem, which is a shortcoming of light scattering methods, through data correction. PM10 and PM2.5 out of the measurement data were used, and when the correction values were applied, the results indicated that the performance was improved in similarity and accuracy.
