Energy use

This is the current waveform in one loop cycle.

• Higher current when SCI on
• Lower current when SCI off (it is actually sleeping)

Let's determine the average.

Imax = 21 mV / 10 Ohm = 2.1 mA

Imin = 0.6 mV / 10 Ohm = 0.06 mA

Ttotal = 265.6 ms

T_Imax = 88 ms

T_Imin = 181 ms

Iavg = (Imax*T_Imax + Imin*T_Imin) / Ttotal 

Iavg = (2.1*88 + 0.06*184)/265.6

Iavg = 0.73 mA
