Data Analysis in Practice
π€οΈ Project Goal
Build a mini weather station that collects environmental data in real time and shows trends with charts:
- Temperature / humidity (DHT22)
- Light intensity (BH1750)
- Air pressure (BMP280)
- OLED display + CSV export
π§ Hardware List
| Part | Qty | Ref. Price |
|---|---|---|
| Arduino main board | 1 | Β₯25 |
| DHT22 temp/humidity | 1 | Β₯12 |
| BH1750 light | 1 | Β₯8 |
| BMP280 pressure | 1 | Β₯15 |
| OLED display | 1 | Β₯18 |
π Analysis Method
- Sample sensor values every 5 minutes
- Remove outliers (extreme values from sensor faults)
- Compute daily avg / max-min / humidity range
- Line chart of the 24-hour curve
