Formulas, units & limitations
Raw bytes/day = nodes × channels × samples/second × bytes/sample × 86,400.
Transmitted payload = raw payload × (1 − reduction/100). Retained GB = transmitted bytes/day × retention days ÷ 1,000,000,000. MB and GB are decimal units.
Sensor-only kWh/year = nodes × average mW × 8,760 ÷ 1,000,000. Theoretical battery days/node = battery Wh × 0.8 ÷ (average mW/1,000) ÷ 24. The 80% usable-capacity assumption is fixed and illustrative.
Payload excludes timestamps, packet headers, encryption, retransmissions, indexing, backups and replicas. Power excludes radios, gateways, processors and conversion losses. The model assumes continuous operation and uniform nodes. Battery self-discharge, temperature, ageing and peak-current limits are excluded. These calculations do not select a device, validate sampling bandwidth or guarantee runtime.
Edge reduction is a user assumption, not an AI performance claim. Zero transmitted payload does not imply zero energy use. Inputs and baselines remain in this page’s memory and disappear on reload.
