PKYDRIP GREENHOUSE CLIMATE CONTROL

From outdoor conditions
to controlled growing environment

One climate control platform for outdoor weather monitoring and greenhouse equipment automation. Controls wet walls, exhaust fans, circulation fans, shade curtains and roll-up ventilation from a single Android industrial controller — with condition-based logic and full event logging.

SYSTEM OVERVIEW

Monitor outdoor conditions. Control the greenhouse environment.

The PKYDrip Greenhouse Climate Control System connects an outdoor weather station to the greenhouse controller, giving the system real data on air temperature, humidity, wind speed, wind direction, light intensity and solar radiation — before those conditions reach the crop.

Inside the greenhouse, temperature and humidity sensors at canopy level feed the same controller. When any measurement crosses a user-defined threshold, the system responds: wet walls activate, fan banks stage on, shade curtains deploy, roll-up ventilation opens or closes. Every action is logged with the sensor reading and trigger condition that caused it.

The system is built on the same Android industrial controller platform as the PKYDrip fertigation system. On S-series and P-series installations, both systems run on the same hardware with separate dedicated interfaces — climate operators see climate data; fertigation operators see fertigation data. The two interfaces do not share screens.

Outdoor Weather Station

Six-parameter monitoring — temperature, humidity, wind direction, wind speed, light intensity, solar radiation.

Greenhouse Sensing

Canopy-level temperature and humidity sensors via RS485 Modbus.

Wet Wall and Fan Control

Wet walls, water pumps, multiple exhaust fan banks and circulation fans — staged activation by condition.

Shade and Ventilation

Shade curtains and roll-up film ventilation, controlled by light intensity or temperature setpoints.

Condition-Based Logic

AND/OR conditions, time windows and sensor averaging prevent false triggering from transient readings.

Full Event Logging

Every action recorded: timestamp, trigger condition, sensor reading, equipment state, run duration.

SENSING

What the system monitors

The outdoor station provides advance warning. If wind speed rises sharply or solar radiation surges, the system prepares equipment before the greenhouse interior is affected.

EQUIPMENT CONTROL

What the system manages

Cooling and Ventilation

EquipmentControl Method
Wet walls (cooling pads)On/off by temperature setpoint; pump interlock enforced
Wet wall water pumpsSequenced with wet wall activation; dry-run protection
Exhaust fansMultiple banks; staged activation by temperature threshold
Circulation fansIndependent scheduling and condition-based control

Shading and Ventilation

EquipmentControl Method
Shade curtainsDeploy/retract by outdoor light intensity setpoint
Roll-up film ventilationOpen/close by greenhouse temperature or manual command

Sequential startup — each group ≤ 2 kW

All equipment groups start in sequence, not simultaneously. Each group is limited to ≤ 2 kW inrush load, protecting generators, transformers and grid connections from simultaneous load spikes. Inter-group delay is configurable from 1 to 60 seconds. Group composition and sequence are confirmed at project configuration.

Condition-Based Control Logic

Every piece of equipment is controlled by user-defined conditions, not fixed timers. Operators set the rules. The system executes, logs and repeats them consistently across every cycle.

Conditions can combine AND/OR logic, time windows and sensor averaging to prevent false triggering from transient spikes in a single reading.

Example conditions

If this conditionThen this action
Greenhouse temperature > 28°CActivate wet wall pump → start exhaust fan bank 1
Greenhouse temperature > 32°CStart exhaust fan bank 2
Outdoor light intensity > 60,000 luxDeploy shade curtain to 70%
Wind speed > 8 m/sClose roll-up ventilation
Greenhouse temperature < 18°C (night window)Close all ventilation

INTEGRATION

Connects to the fertigation system and your platform

Same Hardware, Separate Interfaces

On S-series and P-series installations, the climate control and fertigation systems run on the same Android industrial controller. Each has its own dedicated interface module. Operators see only the data relevant to their task.

Modbus Register Map

All sensor readings and equipment states are accessible via RS485 Modbus RTU/TCP. Connect to any SCADA, PLC or third-party monitoring platform. Register map available to qualified partners.

MQTT Telemetry

Push outdoor weather data, greenhouse readings and all equipment events to ThingsBoard, AWS IoT, Azure IoT Hub or any MQTT-compatible broker.

White-Label UI

Android interface fully rebrandable — logo, color scheme and product name. Available via OEM agreement. Minimum order: 5 units.
