Calculation of monthly data volume:
- Measurement interval: every 20 minutes
- Measurements per hour: 3
- Measurements per day: 72
- Measurements per month (30 days): 2,160
- Data volume per measurement: 2 KB
Total monthly data volume per sensor:
- 2,160 measurements × 2 KB = 4,320 KB ≈ 4.3 MB
This corresponds to the typical monthly data consumption of a single temperature sensor and is consistent with empirical values from comparable applications.
