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:
x
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
x
Determine the total time in Quiescent Low Powered State
Quiescent minutes = 1440 minutes per day – Active minutes
Quiescent minutes = 1440 – 22 = 1418 minutes
x
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
x
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
