DESIGN OF DUST MONITORING SYSTEM FOR PRODUCTION WORKSHOP

As an important place for clean production, real-time monitoring of dust concentration in production workshops is the key to ensuring product quality. Starting from practical application requirements, this article designs a dust monitoring system for production workshops based on STM32. The system integrates PG-03CR six channel laser dust sensor and SHT85 digital temperature and humidity sensor, and combines TFT screen to achieve information visualization and real-time warning function. In addition, through 4G wireless communication technology combined with MQTT communication protocol, monitoring data is transmitted in real-time to the monitoring center, achieving remote monitoring functionality. Through actual testing and comparison verification, the system has maintained good response accuracy and error control in PM2.5, PM10, and temperature and humidity monitoring.
