The Wireless Communication Concentrator is designed for efficient data collection in industrial environments. It comprises a central host (concentrator) and multiple subordinate devices (slaves) that communicate wirelessly. The host unit collects data from all connected slave devices and forwards it to an upper-level system, such as a gateway or PC, via RS485 or RS232 (TTL) interface. This system is ideal for scenarios requiring centralized data acquisition from distributed wireless sensors and devices.
