The Wireless Twig System basically consists of a TD200 Controller, capable of controlling up to 100 Twigs in a programmed sequence. The Twigs are located in the field on solenoid operated valves. The system operates like a conventional hardwired automated irrigation system except the underground wires have been eliminated and replaced by two-way wireless radio signals between the TD200 and the Twigs.
The TD200 and the Twigs that it controls are referred to as a “network”. The Twig system operates in the 900 MHz range and does not require a license. The simple interface of the TWIG and TD200 controller make it easy to automate an entire irrigation system, regardless of the system type or the size of the operation.
