Story

Plant development is impacted by unpredictable weather and climate change, which provide issues for urban farming in Singapore. In order to solve this, we suggest a project that, when required, moves plants within a certain radius to better circumstances using servo motors. Although hydroponics provides a controlled environment for plant development, various portions may experience varied light, humidity, and temperature levels. What if plants could just relocate to the ideal circumstances on their own, without the need for intricate climate control systems?

This project uses a motorized platform to automate the movement of hydroponic plants using the M5GO, a potent and small IoT development kit. Environmental factors including temperature, humidity, and light intensity are continually monitored by the system. The plants are moved to a better setting if the existing one is not appropriate, guaranteeing that they always have the best circumstances for growth.

This technology may maximize plant development, minimize resource waste, and increase production efficiency by dynamically adjusting to changes in the environment. Whether making adjustments for fluctuating sunlight or compensating for temperature shifts, this approach aims to simplify hydroponic farming while maintaining plant health and minimising human intervention
