Smart Public Signage for Optimal Vitamin D
Self-powered by integrated solar panels and micro wind turbines, SunSign displays tell you exactly how long to stand in the sun today based on your skin type, real-time UV levels, and local weather forecasts. Completely off-grid and installable anywhere.
✨ "8 minutes of sun right now = your full daily Vitamin D. UV drops in 12 minutes - catch it now or wait until 3pm!" ✨
