MEI dust monitoring system is the kit IoT Data Logger Developed on microcontroller platform STM32, specialized in collecting, processing and monitoring dust parameters in industrial and outdoor environments in real time. The device is designed to meet the requirements of continuous operation in harsh conditions, suitable for deployment at factories, industrial parks, environmental monitoring stations, mineral exploitation areas, construction sites and air quality monitoring points.
The device supports connection to dust sensors PM1.0, PM2.5, PM10, TSP through communication standards UART, RS485 Modbus RTU or digital interface for each sensor type. Processor STM32 Performs sampling according to configuration cycles, processes and filters signal noise, checks sensor status, calibrates data (Calibration), timestamps (Timestamp) and stores data before transmitting to the server.
The system supports Internet connection via 4G LTE, Wi-Fi or Ethernet (LAN), transmit data to the platform MEI ECO use protocol MQTT, allowing real-time monitoring on Web/App with low latency. Support equipment Continuous Mode, suitable for applications requiring 24/7 continuous monitoring, and Low Power Mode, where the STM32 uses Sleep/Stop modes to reduce energy consumption, only activating the sensor and communication module according to the installation cycle, suitable for battery or solar powered systems.
Integrated equipment Offline Data Logging Use Flash or SD memory card to store data when Internet or server connection is lost. Once the connection is restored, the data will be available automatically synchronizes according to the correct timestamp, ensuring the continuity and integrity of the database. The system also supports Firmware Over-The-Air (OTA), allowing remote control program updates via 4G, Wi-Fi or LAN, helping to upgrade features, fix errors and maintain equipment without direct operations on site.
Users can configure sampling period, data transfer period, calibration coefficient, alarm threshold High, Low, High-High, Low-Low and warning delay time for each dust parameter. When detecting dust concentration exceeding the limit, losing sensor signal or losing device connection, the system will record Alarm Log, and send at the same time Push Notification to the Web/App platform in real time.
Platform MEI ECO Supports centralized management of multiple devices, Dashboard display, trend charts, real-time data, operating history, user authorization and Export Excel report, meets the requirements for monitoring, analyzing and managing air quality in industrial and environmental applications.
