Smart Hydroponics System Integration

I am the founder and project owner of an ongoing project called **Smart Hydroponics – Smart Hydroponics Urban Gardening using AI**.

The objective is to develop an intelligent, automated and scalable hydroponic farming system that combines embedded electronics, IoT, artificial intelligence, automation and software development.

The system is designed to monitor and manage hydroponic growing conditions, automate essential farming operations, analyse plant and water conditions, and provide intelligent recommendations through an integrated software platform.

The project is already under development, and I am looking for experienced individuals who can help complete, integrate, test and optimise the existing system.
