This 4G decoder controller is a professional automatic control device tailored for sponge city rainwater harvesting and irrigation projects. Equipped with a built-in 4G data SIM card, it supports real-time remote operation via mobile phones and computer mini programs. Featuring two hardware configurations of pure 4G and 4G+WiFi dual communication, it ensures stable signal connection for outdoor open-air scenarios. The controller is natively compatible with DC12V/24V pulse and normally closed solenoid valves for direct driving, while AC solenoid valves require an additional relay conversion module. It is widely applied in outdoor unattended rainwater collection projects with stable performance and simple operation.
