Solar-Powered Self Watering Plant System

Dimos and I begun brainstorming ideas for our solar powered project. In our research, we came across a few ‘self-watering plant’ systems such as this and this wanted to take these ideas a step further. We wanted our system to be completely solar powered, thus being an eco-friendly fixture on the domestic plant ecosystem.

 

Materials Needed

  • An enclosure (1)
  • PC Board (1)
  • 5VDC SPDT micro relay (1) **
  • Solar Panel (1)
  • Lithium-Ion Battery (1)
  • Toggle switch (1)
  • 10K resistor (1)
  • Size M coaxial DC power plug
  • Red and black 22AWG wire
  • 12AWG black wire
  • Electric water pump (1)
  • Water storage container w/ lid (1)
  • 8-32 x 2.5″ nuts and bolts (2)
  • 4-40 x 1″ nuts and bolts (8)
  • 4-40 x 3/8″ nut and bolt (1)
  • 1/4″ spacers (4)
  • Wire nut (1)
  • 3′ – 5′ plastic tubing (2)
  • #8 Terminal Ring (1)
  • House plant to water (1)

 

Progress

We are building our own water pump. We found a prescription pill capsule, a 3.6V DC motor and 3D printed spoked wheel. We have drilled, wired and tested the DC motor.

 

Next Steps

We will finish up the water pump, the Arduino code, the circuit and create the enclosure for the pump, Arduino, the battery and a holder for the solar panel.
