MQTT Protocol

Cloud IO-DC series leverages MQTT—a publish/ subscribe messaging protocol for constrained IoT devices in low-bandwidth, high-latency, or unreliable networks—to communicate directly with the cloud or ERP/MES systems without a gateway or converter.


To provide complete IoT solution, the Cloud IO-DC series goes beyond providing a wireless communication interface for sensors—it also provides cloud connectivity for additional user applications. With support for IoT protocols such as REST and MQTT, the Cloud IO-DC series can communicate with cloud services or other web services via secure web sockets.


Advances in IoT have led to the development of many wireless technologies that can be applied in a variety of hardware products. The Cloud IO-DC series supports secure Wi-Fi connectivity to meet specific wireless needs.

"The process of creating an IoT device is complex, involving the integration of hardware and software. However, the results of this approach result in devices that are more secure, faster, and more user-friendly. Integrating hardware and software allows for better performance and easier maintenance of devices. Additionally, this approach enables IoT devices to be more scalable and developed more quickly. Ultimately, integrating hardware and software in IoT should be seen as an important way to create stronger and more efficient devices."
