In the age of smart agriculture, precision environmental control is key to optimizing crop yield and quality. This OpenPLC-based automation solution demonstrates how a 50-mu (approximately 3.3 hectares) connected tomato greenhouse leverages edge computing and I/O flexibility for fully autonomous and remotely accessible climate regulation.
? Application Scenario
Smart Tomato Greenhouse – 50-Mu Cluster
To maintain ideal growing conditions, the greenhouse requires real-time monitoring and dynamic control of temperature, humidity, CO₂ concentration, and light intensity. An automated control system powered by the ARMxy Edge Controller and OpenPLC ensures that environmental factors are continuously monitored and adjusted.
? System Configuration
- ARMxy Main Controller – Runs OpenPLC logic and communicates with remote systems via MQTT/cloud interface.
- Y-AI Board – Collects analog signals from environmental sensors (CO₂, light, temperature, humidity).
- X-DO Board – Controls actuators including roof vents, exhaust fans, grow lights, and drip irrigation valves.
