To estimate the power consumption of the system, look up the
parameters in Table 16-1, along with the communication times to
calculate the power consumption as follows:

Determine the Active Time in minutes:
Active Minutes = Number of pictures per day * (Active
Du Communication Time)/60
For a camera in the
Deep Sleep state sending 24 photos
per day at 115200 BAUD that are 100 Kbytes in size:
Active Minutes =24*(25 s 30 seconds)/60 = 22
minutes/day of Active Time

Determine the total time in Quiescent Low Powered State
Quiescent minutes = 1440 minutes per day – Active
minutes
Quiescent minutes = 1440 – 22 = 1418 minutes

Determine the power consumed by the Quiescent state in
Amp-Hours.
Quiescent power = Quiescent minutes * Quiescent
Current Draw/60
Quiescent power = 1418 minutes*6 mA/60 = 141.8 mA-
Hour or
0.1418 Amp-Hours/Day

Determine the power consumed by the Active state in
Amp-Hours.
Active power = Active minutes * Active Current Draw/60
Active power = 22 minutes*250 mA/60 = 91.67 mA-Hour
or
0.0917 Amp-Hours/Day

Total power consumption is the sum of the Active and
Quiescent Power
Total power = Quiescent Power + Active Power
Total power = 0.1418 Amp-Hours/Day + 0.0917 Amp-
Hours/Day
Total power = 0.2335 Amp-Hours/Day
