hello everybody,
please suppport & share our mission; igg.me/at/smartplants
today i would like to share with you how I solar charge my smart plant pots. a smart plant pot looks just like a regular plant pot but it can email you when your plant needs attention (too hot/cold, thirsty, sleeping etc.)
and with the solar charge upgrade, it can alarm you forever !!
a self sufficient smart plant system..
.
we will need;
solar cells - http://www.ebay.com/itm/5V-0-8W-160mA-Mini-Solar-P...
zener diode - http://www.ebay.com/itm/Values-2V-47V-1-2W-0-5W-Ze...

-
chopsticks
foamboard
.
hot glue
solder
.
this instructable will teach you how to make a solar charger for your power bank. this scenario can easily be adapted to other projects that need re-charging.

get the hot glue gun ready.
-
start by tracing 2 solar cells side by side on foamboard.
after tracing cut out the board, save the cut out and use it as the back wall.
-
hot glue the back wall to the sides, and cut and extra foam on sides.
Wires

put your solar cells in to the frame and turn it around
.
figure out where the pins are located, draw and cut out some holes.
Legs

find some chopsticks and glue them to each side of the frame as legs.

i was able to get upto 6.5V from a 23W CFL bulb and 5.85V in full sun.
.
here you can also see the cells charging the powerbank using CFL lighting once again.

this instructable is about how to power the explained system below using solar energy.
.
power bank is the most crucial element of our system. it is a battery holder and a charger in a sleek protective case.
it accepts 5Vin to recharge and provides 5Vout to power things up.
.
connected to it, arduino nano is reading sensor data (water level, temperature, light level). the data is uploaded to thingspeak.com, where it gets plotted into graphs.
.
if the collected sensor data is above/below certain levels, the system alarms the user both in person by changing color, and also sends a tweet to your email account.

please vote for me in the Make Energy contest. I need a 3D printer to be able to finish my educational kits.
.
our kits teach how to program microcontrollers and build circuits. a solder-free electronics learning kit, suitable for any age group.
.
and after finished with the kit, the user will have a functional device that teaches them how to grow plants. no prior electrical/gardening experience required.
.
meet the Plant Doctor family.
