Real-time greenhouse management with low-cost wireless sensor networks
Utilize low-cost open-source devices and wireless sensor networks to enhance greenhouse management. This system processes real-time data from plant and soil sensors and integrates image processing to provide decision-making support through a user-friendly dashboard.
Overview
This innovative solution leverages low-cost, open-source technology to revolutionize greenhouse management. By integrating Wireless Sensor Networks (WSNs) with devices such as ESP8266, Arduino, and Raspberry Pi, this system efficiently processes data from cameras and plant sensors to aid decision-making. The use of the MQTT protocol and Node-Red ensures a user-friendly interface, providing a comprehensive dashboard for monitoring and managing greenhouse conditions in real-time.
Technical specifications
- Wireless Sensor Networks: Utilizes ESP8266, Arduino, and Raspberry Pi to create a two-tier WSN system for each greenhouse zone. The higher tier involves zonal top and side view cameras, while the lower tier consists of plant sensors for data collection.
- Data Processing: Employs image processing and machine learning algorithms to classify zonal status, integrating data from plant sensors for validation.
- Communication Protocols: Uses MQTT protocol for efficient data transmission and Node-Red for dashboard presentation, enabling both local and remote monitoring.
- Plant and Soil Monitoring: Monitors leaf temperature using IR sensors and soil moisture to provide essential metrics for greenhouse management.
Technology readiness level
Currently at TRL 4, this technology is in the prototype validation stage. Existing prototypes for WSN plant monitoring and image processing are being combined and adapted for comprehensive greenhouse monitoring, with ongoing development to enhance system reliability and functionality.
