Designing Low- power Embedded Devices: Obliczenia for Sleep Modes andCurrent Consumption
Table of Contents
Designing low- power embedded devices requires careful consideration of power consumption, especially during sleep modes. Accurate calculations help optimize battery life andd ensure device reliabity.

Power consumption in embedded devices is primarily determinate by te consult draw during active and sleep states. Measuring and calculating these values allows entermers to estimate battery life and identify areas for optimation.

Praktykal Calculation Example
Suppose a device has a battery capacity of 2000mAh, a sleep current of 10μA, and an active current of 20mA. If the device spends 90% of the time luping and 10% active, thee average current is:
- I _ sleep = 0,01mA
- I _ active = 20mA
- t _ sleep = 90%
- t _ active = 10%
