Ultra-Low-Power Weather Station

I designed the weather monitor on nRF52832 using Waveshare 2.13” ePaper display and environmental sensors via I2C. Fruthermore, I implemented barometric pressure trend analysis using 30-minute circular buffer; calculating thresholds for prediction. Lastly, I optimized firmware using Nordic SDK with RTC-triggered wakeups; ePaper bistability minimized power consumption.
