Twig Wireless Control Systems turn valves on and off in the most simple and reliable way possible. It allows you to put the right amount of water where you need it most while reducing labour requirements, unnecessary features, and troublesome wires. The newest generation consists of a “master controller,” the TWIG-MC, that communicates via 900 MHz radio signal with TWIG devices (nodes, or RTUs) installed in the field next to solenoid-operated irrigation valves. The TWIG-MC is programmed and operated using a mobile app (iOS or Android) and controlled via Bluetooth® or an internet connection.
