Industrial IoT Gateway Kit is a device that collects, processes and transmits data MEI Group researches, designs and develops, use the platform Raspberry Pi 5 (RAM 8 GB) combines a touch display screen, meets the requirements of local data processing, visual monitoring and connection to SCADA systems, Cloud or central server. With a high-performance processor, the device allows simultaneous operation of multiple tasks such as data collection, logging, communication, HMI interface display and real-time processing of monitoring algorithms.

Gateway is integrated with a variety of industrial communications including RS485/Modbus RTU, entrance high speed pulse, analog input 4–20 mA, digital input (Digital Input) and control output (Digital Output), allowing connection to flowmeters, pressure sensors, water level, pH, DO, EC, ORP, COD, TSS, meteorological sensors, power meters and many other field devices. The system supports expanding the number of devices through a multi-point RS485 network, meeting the requirements of monitoring stations with many sensors.

The device supports network connection Ethernet, Wi-Fi and 4G (optional), transmit data according to standard protocols such as MQTT, HTTP/HTTPS, Modbus TCP and TCP/IP, ensuring integration with multiple management and monitoring platforms. Gateway has local storage to record data and event logs when network connection is lost, and automatically synchronizes all data to the server when the connection is restored, ensuring data continuity and integrity.

Integrated system Real-time RTC, device status monitoring mechanism, automatic restart when there is a problem, remote software updates (OTA), remote configuration and user authorization to reduce operating and maintenance costs. The integrated display allows display of communication status, sensor values, alarms and operating parameters right in the field.

With industrial hardware architecture, 24/7 continuous operation, anti-interference design and easy expansion, IoT Gateway is the right solution for systems automatic wastewater monitoring, groundwater monitoring, surface water quality monitoring, hydrology, water supply, environment and industrial IoT applications, meets the requirements of accurate data collection, stable data transmission and real-time centralized management.
