1.4 Power Consumption Breakdown

NE301's daily power consumption consists of two components:

Capture Power (Dynamic): Device wake-up, image capture, AI inference, data upload

Daily Capture Power = (Operating Current × Operating Duration × Capture Count) / 3600

Standby Power (Static): System maintenance during sleep state

Daily Standby Power = (Deep Sleep Power × 24 hours) / 1000
= 6.1 μA × 24 hours / 1000
= 0.146 mAh
≈ 0.15 mAh

Power Consumption Distribution:
