rainwater harvesting system 3d model

create a simple low-poly 3d model of a rainwater harvesting system. include a samll titled roof, a starigth pipe from the roof into a cylindrical water tank and a mesh at the top of the pipe as a rain catcher . add multiple simple sensors around the system : a water level sensor on the tank, a rain intensity sensor near the roof, a flow sensor on the pipe, an overflow sensor on the top of the tank, and a leakage sensor near the bottom. also add a small square IoT control box on the side. keep the model clean, minimal and easy to understand for college project.
