Power Circuit

Power needs are

12 LEDs requireapproximately 3 v and 25 mA

eZ430-RF2500 requiresapproximately 3 v and 20 mA

Total mAh is 12*25*1h+20*1h = 320mAh

Power solution 2 TX3-25

photovoltaic cells in series

connected to a lithium ion

battery

TX3-25 typical voltage is 3v

with 2 in series= 6 volts

Lithium ion battery voltage3.7 and 740mA/h

740mA /h 320mA /h=420mA/h

We can run for 2 hours on afully charged battery!

Solar Cells

Concerns?

Power rating is given based on

AM1.5 ~ what does this mean?

This means that at 25 C and

perpendicular to the sun this is

the power you can expect to

achieve from this solar cell.

Will not always have this kind

of out put.

Solutions?

Design panel that will rotatewith the sun path through the

sky maintaining an optimal

angel

Depending on where the unit

is sold more cell might have tobe added.

Limitations?

Map of the worlds solar

activity

The amount of solar activity

will also effect the power

output of the cells
