Agricultural Irrigation Application
Agricultural sensors are connected to the USR-DR206 and transmit data to the data control center via a LoRaWAN gateway, enabling rapid long-distance data exchange and control. This setup allows for real-time monitoring and management of irrigation, pest and disease, and fertilization, which in turn reduces the need for on-site personnel, enhances the overall farm management level, increases economic efficiency, and lowers operational costs.
