MEI IoT Demo Kit is a platform for demonstrating and developing applications Industrial IoT, built on a microcontroller STM32 to fully simulate the architecture of a data acquisition, monitoring and remote control system. The device integrates many industrial communications such as Digital Input (DI), Digital Output (DO), Analog Input (0–10V, 4–20mA), RS485 Modbus RTU, allowing connection to sensors and peripherals in many practical applications.

Data from sensors is processed in real time by STM32, performing noise filtering, signal conversion, status monitoring and continuous updating. HMI screen. Operators can directly monitor sensor values, input/output status, control relays, turn lights on/off and change operating parameters right on the HMI interface.

Devices that support connection Ethernet (LAN), Wi-Fi or 4G LTE, transmit data to the platform MEI ECO through protocol MQTT, allowing real-time remote monitoring and control on Web/App. All control commands from the Web/App are instantly synchronized to the device and status feedback is given to confirm the execution process.

Integrated system Offline Data Logging, stores data and event logs when network connection is lost, then automatically synchronizes to the server when connection is restored. Users can configure the alert threshold for each signal, send Push Notification when there are unusual events, manage multiple devices on the same platform, assign user rights, display Dashboard, trend charts and Export Excel report, effectively meeting the needs of training, research, testing and demonstration of industrial IoT solutions.
