As the integration of IoT and cloud computing technologies advances, they are increasingly being utilized to address global challenges in agriculture, such as feeding a rapidly growing population. The text outlines how smart farming, enhanced by Agri-Tech companies like Illuminum Greenhouses, leverages IoT to precisely monitor and manage agricultural resources, thereby promoting sustainable food production. It provides a comprehensive guide on building an IoT-enabled self-sustaining plant system using a Raspberry Pi, sensors, and PubNub’s real-time data infrastructure. The system includes components like a submersible water pump, temperature/humidity sensor, and soil moisture sensor, all of which are integrated with PubNub’s platform to facilitate real-time monitoring and control. The project highlights the potential of IoT in creating efficient and sustainable agricultural practices, offering instructions for setting up and coding the system to automatically manage plant care through a combination of automated and manual modes. This innovative approach not only emphasizes the importance of technological adoption in agriculture but also serves as a model for developing scalable and sustainable farming solutions.
