Planterbot – The Plant Monitoring Robot

Hello everyone !

Please vote for me in the tech contest!

In this instructable I am collaborating with Akin Yildiz an instructables author that creates instructables that help plants grow you should really go check out his account:


The planterbot is a plant monitoring robot. It uses capacitance for sensing moisture from the plant instead of using the usual soil probe, this means that wires don’t go into the plant. It also detects temperature and light using thermistors and Cds photocells and displays the temperature and light graphically on the front facing LCD.

This is kind of like the the final version of Akin’s :…

Note: Currently you should power this from a 9 volt battery pack, if you don’t do this and power it off of an AC wall outlet the readings will be off.

Update: New youtube video of it! another one will be coming soon that shows off all of the features.

Here is how the idea of the collaboration started:…

Step 1: Parts and Tools

These are the parts and tools that you will need to make this project:


Arduino Uno or Leonardo with USB cable

Thermistor 10k ohm

Cds photocell (light sensor)


Electrical tape

Battery pack for arduino with DC plug 9v

Small amount of aluminum foil (for water sensor)

Baltic birch or anything that is laser cuttable.

The Plant Monitoring Robot

Acrylic for water sensor (you can use wood for the water sensor but it doesn’t look as good and the wood can warp if it gets wet.)

Male headers

16×2 LCD preferably with backlight


Laser cutter

Computer with arduino IDE

Hot glue gun and hot glue
