Solar-Powered Weather Display Using Tri-Color E-Paper Screen
Ricardo Sappia’s solar-powered weather station features a 2.13-inch tri-color (black/white/red) e-paper display with 250×122 pixel resolution. Powered by a compact solar panel for window-mounted charging, the device shows:
-
Time & date
-
Sunrise/sunset times
-
Daily high/low temperatures
-
Wind speed/direction
-
Cloud cover conditions
At its core, an ESP32 controller fetches live weather data and updates the energy-efficient e-paper screen, which then enters deep sleep mode between refreshes to maximize power savings.
