Design and Implementation of Construction Site Dust Monitoring System

With the development of modernization, urban and rural construction, the pressure on the environment caused by site construction is increasing. Construction site dust is one of the sources of PM2.5, if there is no strict supervision, the dust generated by construction will have a great impact on the surrounding environment and people's lives. In order to better manage and monitor the environmental state on the construction site and save financial, material and labor costs, a set of site dust monitoring system is designed. This system is based on STM32 single chip microcomputer as the core, combined with environmental data collection, screen display, data upload, GPS positioning in one of the dust monitoring system. The system uses STM32 MCU as the main control core, and the collected data can be uploaded to the remote server through the 4G communication module. The system has the characteristics of real-time acquisition, real-time upload, stable data, small size, easy installation, etc., which is fully suitable for dust monitoring in outdoor construction sites.
