Measurements are periodic
Temperature, humidity, CO2 and soil moisture may only be checked a few times each day.
Smart Greenhouse
Environmental Monitoring and Equipment Automation
Connect temperature, humidity, light, CO₂ and soil-moisture sensors to YenGear IoT Cloud, then connect fans, cooling pads, pumps, curtains and grow lights by project. View each zone and configure control rules from one system.
WiFi / Ethernet / 4GIP65 industrial I/OMulti-greenhouse group control
A control system for greenhouse zones
Each zone has its own sensors, loads and operating rules. YenGear connects these points to a shared monitoring and control interface.
Use wired or wireless links, configured automation and cloud records according to the site and the crop.
Common greenhouse control problems
Manual rounds and distributed equipment make it difficult to respond at the right time.
Equipment is distributed
Fans, irrigation, curtains, pumps and lights across several zones make local control time-consuming.
Night conditions go unseen
Cold fronts, storms and humidity changes can occur between manual inspections.
Records are incomplete
Without consistent history, teams must rely on memory when comparing growing cycles.
Connect each zone to the control platform
I/O modules collect temperature, humidity, light, CO2 and soil moisture readings across greenhouse zones.
Configured cloud rules can trigger fans, vents, shade curtains, irrigation pumps, grow lights and heaters. Operators can review status, records and alerts from a phone or desktop.
- Wired Ethernet
- WiFi
- 4G LTE
Greenhouse Monitoring and Control Sequence
Set up zones, define rules and review the operating record.
Measure each zone
I/O modules collect temperature, humidity, light, CO2 and soil moisture readings.
Apply configured rules
Readings reach YenGear IoT Cloud over WiFi or wired Ethernet, where rules trigger equipment or alerts.
Review actions and records
Use current status, event history and exports to compare growing cycles and adjust the operating plan.
Functions for daily greenhouse operations
Monitor conditions, control equipment, notify staff and review records in one operating view.
Zone monitoring
Track temperature, humidity, light, CO2 and soil moisture on the dashboard.
Automated control
Run rules such as temperature-triggered fans, dry-soil irrigation, shade curtains, or grow lights.
Group control
Open vents, start irrigation or switch grouped equipment from one phone screen.
Multi-channel alerts
Send app, SMS, or email notifications with the greenhouse, zone, reading, and alert level.
Historical records
Store readings, equipment actions, and alerts for reports by day, week, month, or growing cycle.
Network options
Use WiFi, wired Ethernet or optional 4G backhaul according to the site.
Examples by crop and operation
Rules and equipment vary by crop, site and growth stage.
Tomatoes, cucumbers, and peppers
Ventilation, fan, drip irrigation, and CO2 rules for tomatoes, cucumbers, and peppers.
Roses and lilies
Light, shade, supplemental lighting, temperature, and humidity control for roses and lilies.
Nursery work
Tighter temperature, misting, humidity, and gradual light ramping for nursery work.
Specialty crops
CO2, humidity, fresh-air intake, fogging, and strict temperature-band alerting.
Operating approach
The system combines zone data, equipment control and records for day-to-day greenhouse work.
| Generic IoT platform | YenGear smart greenhouse solution |
|---|---|
| Sensors, protocols, dashboards, and logic often require IT configuration. | Mount modules, connect zones, name equipment, and use growing rules your team understands. |
| Automation builders are written for industrial engineers. | Rules read like greenhouse practice: if temperature is high, open vents and start fans. |
| Multi-greenhouse management may require separate dashboards or enterprise tiers. | Greenhouses, crop groups, zones, alerts, and group control share one operating view. |
| Reports often start as raw data exports. | Environmental records are organized for growing-cycle review and audit preparation. |
Deployment example: 50-greenhouse vegetable operation
A representative configuration for a vegetable operation.
The operation: 50 greenhouses across 8 hectares, growing tomatoes, cucumbers, and peppers for regional supermarket chains.
The challenge: Morning rounds took three workers more than four hours, winter night drops caused annual cold-stress losses, and group equipment changes required long walks.
The deployment: I/O modules across multiple greenhouse zones, with temperature and humidity sensors, soil moisture probes, light sensors, mixed WiFi and wired networking, and staff training.

Greenhouse deployment questions
Answers about installation, networks, rules, outages, records, scale and project scope.
How long does installation take?
Installation depends on greenhouse count, zones, sensors, existing networks and access conditions. We confirm the schedule after a site review.
What if our greenhouses do not have WiFi?
The site can be assessed for wired Ethernet, industrial WiFi access points or cellular backhaul. The choice depends on zone distance, power, network coverage and installation conditions.
Can non-technical growers change rules?
Users can change the rules permitted by their role. The available conditions, actions, approvals and pre-configured templates depend on the deployment and should be confirmed during setup.
What happens if the internet goes down?
Local measurement, buffering and pre-configured automation can continue when the selected controller and project configuration support them. Cloud commands and records synchronize only after the connection returns.
Can it support organic or GlobalG.A.P. records?
Environmental history can be exported for a selected date range and used as input to audit preparation. Whether the data and format satisfy a particular scheme or buyer requirement must be confirmed with the responsible auditor or customer.
Can one system handle multiple greenhouses?
The platform can organize greenhouses, zones, crop groups, rules, team access and group controls. Confirm the supported scale and deployment model for your project.
How does pricing work?
Pricing depends on greenhouse count, zones, sensors, control points, network and integration requirements. Scope, options, lead time and quotation terms are confirmed after the project information is reviewed.
