Industry Background
Modern global agriculture faces intense systemic operational bottlenecks, including critical rural labor shortages, strict water resource constraints, and fluctuating climate cycles. To secure maximum crop yield stability and reduce environmental runoff, agri-tech integrators require absolute control over chemical distribution. Traditional manual dosing introduces high variable errors, making real-time closed-loop sensing essential for precision asset management.
System Overview
Samkoon’s integrated display control solution optimizes precision irrigation and chemical fertilization loops within a single, industrial-grade hardware ecosystem. By synchronizing high-accuracy sensor data with automated dosing manifolds, this hardware-centric platform enables farms to manage localized soil feeding rules, eliminate chemical waste, and lower daily operational labor overhead across greenhouses, vertical farming cells, and open-field installations.

Intelligent Operation Modes
| Operation Mode | Technical Control Execution Profile |
|---|---|
| Manual Mode | Field operators execute direct, isolated manual overrides for auxiliary chemical valves, solenoid manifolds, and primary pressurization pumps via the HMI window registers. |
| Auto Fertilization Mode | The PLC continuously reads feedback loops from localized pH and EC sensors, executing automated PID proportional adjustments via chemical dosing valves to maintain precise nutrient ratios. |
| Circulation Mode | The program logic executes automatic, time-delimited irrigation cycles, supplying pre-mixed nutrient solutions at fixed, repetitive chronological intervals based on crop recipes. |
| Irrigation Mode | Specialized water-only flushing and irrigation cycles executed over static, pre-configured duration windows to manage soil salinity tracking. |
All real-world operational parameters—including real-time pH scales, EC conductivity levels, cumulative volumetric flow rates, and chemical usage logs—are recorded within local non-volatile registers and continuously synchronized to the upstream Samkoon Cloud 3.0 platform for advanced data analytics and remote management tracking.
