ORGANIC WEATHER STATION

The "Organic Weather Station" blends botanical aesthetics with robotics, creating a responsive flower-like robot. Equipped with photodiodes, a stepper motor, and an ESP32, this design emulates the natural behavior of flower petals that open and close with changes in light levels. It demonstrates a harmonious integration of components, providing both environmental feedback and decorative value in indoor settings.

Features

• Adaptive Petal Movement: Responds to light intensity data from photodiodes, controlling the movement of its petals to mimic natural responses.
• Environmental Feedback: Responds to light intensity data from photodiodes, controlling the movement of its petals to mimic natural responses.
• Remote Weather Updates: Connects with a Telegram chat to retrieve and display weather conditions from any specified location.
• Ambient LED Effects: Incorporates LEDs within the petals that shift colors based on the ambient room temperature.

Because it is still in process, below you can see the layout of the plant: If you are interested in carrying out this project, we invite you to the following sections!

MECHANICAL PART

3D printed parts

For the movement, we use a mechanism that consists of a worm gear that rotates by a stepper motor, attached to the worm gear are four gears, that have the petals of the plant, these ones rotate and the petals move upside down mimicking the movement of the aperture of a plant in the wild. Here below you can see all the parts needed to be able to make this mechanism and an explanation:

GEAR ATTACHED TO THE PETALS, rotates to a certain point for the aperture and closure of the flower

WORM GEAR, on the lower end, has a dent to be able to put together the stepper motor for the rotation

HOLDER FOR THE GEARS TO MOVE WITH THE WORM GEAR, this piece holds together the center of the worm gear vertically, and in each of the four sites it goes a GEAR with a petal
