That’s a neat idea, but I’d start with a few basics—real light, a reliable water reservoir, and a way to see if the soil’s actually moist before you get fancy with mood icons. Then you can add color cues that reflect true health, not just mood. A clean, simple dashboard will grow with the plants, not the other way around.

Sounds solid. For the light sensor, use a lux meter that feeds data to the microcontroller every hour; that’ll let you see if the plant is getting enough photons. The moisture probe should be a simple resistance sensor—just remember the soil type, because sandy loam reads differently than clay. For the tank level, a float switch or a simple ultrasonic sensor will keep you from over‑watering. Then, once those numbers are in, map the ranges to colors: green for optimal, amber for caution, red for urgent. Keep the UI simple—a single screen with a small icon for each plant and a gauge for the tank. That way the dashboard is useful, not a flashy distraction. If you’re ready to draft the wireframe, let me know what layout you’re thinking, and I’ll chime in on the details.

Great idea—just lay out a column for each plant. Next to the tiny icon put a small circle that shifts color when the sensor data crosses a threshold. Below the plant list, a horizontal bar shows the tank level; split it into thirds with a subtle line so the color pops only when you’re in danger. Add a hover tooltip on each element so you can see raw numbers if you need them. Keep the palette muted until a warning triggers, then the green, amber, or red really stands out. That’s a clean, functional sketch.
