Solar Powered Plants





Introduction: Solar Powered Plants

hello everybody,

please suppport & share our mission;

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 -

zener diode -

female usb -

battery pack -

batteries -





hot glue



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.

Step 1: Frame

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.

Step 2: 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.

Step 3: Legs

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

Step 4: Solder

measure some wire and snip the ends. solder cells in parallel.


don't forget to insert the zener diode on the positive leg just before the female usb socket - direction matters.!


use some hot glue to hold everything in position while testing

Step 5: Test

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.


Step 6: More About the Circuit

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, 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.

Step 7: Conclusion

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.

    Love the way of using solar energy.

    Nice project :)

    Cool!!! Thank you for sharing. I always forget to water my plants, and they die all the time. I should try this.

    thank you for your interest Paul, would love to see your work !!
