Greenhouse farming plays a crucial role in modern agriculture, enabling year-round cultivation, improved crop yields, and better resource management. However, traditional greenhouse systems require constant human monitoring and intervention, leading to inefficiencies and labor-intensive processes.
This project aims to develop an IoT-based Smart Greenhouse Automation System to optimize environmental conditions, enhance productivity, and minimize manual intervention.
-
Remote Monitoring & Control
Mobile app integration for real-time access and adjustments. -
Automatic Irrigation Control
Irrigation automatically adjusts based on soil moisture levels. -
Automatic Nutrient Control
Nutrients are dispensed as needed based on environmental and crop conditions. -
Data Analysis and Summary
The system analyzes historical data and provides useful summaries for better decision-making.
A demo video is available to illustrate the working system:

The mobile app developed using React Native allows users to:
- Monitor live sensor data
- Trigger irrigation or nutrient pumps
- View summarized analytics and control settings
- Uses AWS IoT Core for device communication and MQTT protocol for real-time messaging.
- Device data is sent to the backend and stored in MySQL for analysis.
This system automates and modernizes greenhouse management by integrating IoT, cloud computing, and mobile technologies. It offers a scalable, efficient solution for smart agriculture.
