Calculation of Power Consumption
- Battery
- Power consumption for main circuits on MI6
1. LED indicators ( X 4 )
P1 = 3.3V * (3.3V - 1.8V) / (150 ohms) * 4 = 132 V.mA
2. Joystick ( X 1 )
P2 = (5V)^2 / (5k ohms) * 2 = 10 V.mA
3. 7 segment display ( X 2 )
P3 = 5V * (5V - 1.8V) / (47 ohms) * 2 = 681 V.mA
4. Xbee ( X 1)
P4 = 3.3V * 50 mA = 165 V.mA
- Estimated duration
Thus, our design meet the requirement of at least 8 hours of usage.
