GWMS – Gateway Module System is a scalable IoT architecture developed by Demsay for industrial IoT, defence electronics, remote monitoring, automation, and smart infrastructure applications. The system consists of a central gateway and distributed field modules.

The central gateway integrates wired and wireless communication technologies, including LoRa, Wi-Fi, Bluetooth, LTE, Ethernet, CANBus, Modbus, and RS232, within a single platform. This architecture enables data from multiple field locations to be collected, processed, transmitted, and centrally managed.

GWMS field modules operate as low-power sensor nodes. NanoPower-based intelligent power management supports time- and event-triggered data transmission, helping optimize energy consumption and extend battery operation.

Developed with ESP32-S3 and industrial-grade microcontrollers, the system provides edge data processing, reliable communication, energy-efficient operation, and integration with various field devices. Its modular architecture allows sensors, communication interfaces, and peripheral devices to be configured according to specific application requirements.

GWMS – Gateway Module System provides a flexible infrastructure for telemetry, distributed sensor networks, vehicle and platform subsystem monitoring, facility and environmental condition monitoring, remote control, field data acquisition, smart infrastructure, automation, and defence electronics development.
