Design of PM_2.5 and PM₁₀ measuring instruments for analysis of air pollution distribution patterns in the dramaga area based on internet of things

Particulate Matter (PM) is the main material commonly used to show the degree of air pollution. PM material has an impact on human health and the visibility of the atmosphere. Standard gravimetric measurements and current commercial instruments for field measurements are still expensive and limited at several points in Indonesia. In this research, a low cost PM_2.5 and PM₁₀ measuring instrument was designed, with the application of the Internet of Things (IoT) to support real-time monitoring. This instrument can be used to increase the spatial and temporal resolution of PM data. The system uses the ZH03A which has a correlation of 0.8936 in PM_2.5 and 0.8873 in PM₁₀ through comparison with standard instrument. Sensor data is processed by a data logger which is connected to the internet via the ESP8266 module. This module has sent data to the database with 0% data loss on testing and sent to display the actual PM_2.5 and PM₁₀ values in a website. The results showed a negative correlation on temperature and positive correlation on humidity. The measurement system has recorded the distribution patterns of PM coming from the northwest of Dramaga.
