BME280 Typical Power Consumption Estimates (See datasheet for full estimation):

Mode	Average Current	Description
Sleep Mode	< 0.1 µA	The sensor is inactive, consuming minimal power until a measurement is triggered.
Forced Mode	~0.6 mA	Takes a single measurement and returns to sleep mode to save power. Ideal for periodic readings.
Normal Mode	~1.8 mA	Continuously takes measurements at a defined interval, providing real-time data updates.
