As smart agriculture and urban landscape management rapidly shift toward refined, unmanned operation, the controller — the heart of any irrigation system — is undergoing a profound transformation, evolving from a simple timer‑switch to an intelligent command hub. Rooted in Central China, Zhengzhou Yayuan is a technology‑focused enterprise specialising in smart water circulation and intelligent irrigation. Its newly‑launched CJ100 Decoder‑Controller serves as a custom‑built “smart brain” designed for modern farms, municipal green spaces and large‑scale greenbelt projects.

Dual‑Line Decoding: Redefine Control Logic for Large‑Scale Irrigation
Traditional irrigation systems are often constrained by complicated wiring layouts and limited control distances. Adopting advanced two‑wire decoder technology, the Zhengzhou Yayuan CJ100 Decoder‑Controller transmits both power and control signals over a single twisted‑pair cable to build a robust HSBUS bus network. This technical innovation cuts cable consumption by 30%‑80% and enables effortless system expansion. Whether you add a new lawn section or expand an orchard, you only need to connect new decoders to the main cable.

Support for Up to 100 Stations, Ultra‑Long‑Distance Coverage
The CJ100 delivers powerful station‑management capacity, supporting a maximum of 100 irrigation zones to meet complex zoning requirements for medium‑to‑large irrigation projects. Powered by HSBUS bus communication technology, control signals can travel up to 3 kilometres. With stable 24 V AC solenoid valve driving capability, it effectively solves the voltage‑drop issue over long‑distance wiring. Centralised management is now achievable for vast farmland, multi‑kilometre golf courses and municipal green belts.
One‑Screen Centralised Control, Integrated Hardware‑Software Experience
For user interaction, the CJ100 is equipped with a responsive LCD touchscreen and a full‑Chinese human‑machine interface, eliminating cumbersome button‑based programming. Operators can set customised irrigation schedules for different zones to achieve precise rotational watering. Most notably, it supports remote control via mobile APP. Managers can check device status and adjust irrigation plans anytime, anywhere without on‑site visits, turning the “farm at your fingertips” concept into reality.

Heavy‑Duty Protection for Harsh Outdoor Environments
Engineered for the variable climatic conditions across Northern China, the CJ100 features an outdoor enclosure built from high‑strength ABS engineering plastic with an overall IP65 protection rating, shielding internal components from rain, wind and prolonged sunlight exposure. Its unique double‑door design delivers improved anti‑theft performance and provides an extra layer of protection for electronic parts during extreme weather, guaranteeing long‑term stable operation in field sites, parks and other outdoor locations.

Deep Integration to Build a Complete Smart Irrigation Ecosystem
As the core hub of your irrigation system, the CJ100 offers outstanding openness and expandability. With a built‑in HSBUS module and power transformer, it is ready for out‑of‑the‑box deployment with no extra assembly required. It seamlessly works with the full range of Zhengzhou Yayuan smart decoders, including soil‑moisture sensor decoders, rain‑sensor decoders and AC/pulse solenoid valve decoders, forming a complete closed‑loop workflow from environmental sensing and intelligent decision‑making to field execution. Additional external expansion ports are reserved for weather stations, flow meters, air pumps and other peripheral equipment, making future upgrades to water‑fertiliser integrated systems straightforward.
The Zhengzhou Yayuan CJ100 Decoder‑Controller is far more than a control unit. It bridges conventional irrigation infrastructure and the next‑generation smart‑agriculture era. Boasting reliable performance, intelligent operation and flexible expandability, it has become a trusted upgrade solution for large‑scale irrigation projects of all types.
