HybridNET management and sensor data acquisition system

Abstract

In this work, we present the HybridNET management and data acquisition system, which we created for the control and monitoring of large air-conditioning installations in industrial buildings and shopping malls. The system uses an 868 MHz internal network communication based on LORA and it is equipped with a GPRS gateway that connects to a control center on the Internet. It has been successfully tested in two Bulgarian shopping centers and up to this point it performs its functions very well.
