6.1.1 Usage Scenario 1

In Scenario 1, assume the switch polls the light every 5 seconds and toggles the light 20 times a day. Assuming there is no communication failure, this scenario has (60 x 60 x 24 / 5 – 20) = 17260 times of Operation2, 20 times of Operation3, and 20 additional times of Operation2. Therefore, the total per-day charge consumption CCTOTAL is calculated as shown in Equation 2.

Equation 2. C C T O T A L   =   C C S L E E P + C C O p e r a t i o n2   *  17260   +   C C O p e r a t i o n3   *  20   +   C C O p e r a t i o n2   *  20 C C T O T A L   =  69120   m A   +   (6 .1   m A   *  6 .3   m s   *  17260 )   +   (6 .5   m A   *  9   m s   *  20 )   +   (6 .1   m A   *  6 .3   m s   *  20 ) C C T O T A L   =  734 ,360   m A m s C C T O T A L   =  0 .204   m A h

And, the battery life can be calculated as shown in Equation 3.
