Overview
Octoplant is an open-source printed circuit board by harry48225, from the harry48225/octoplant repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 15.2 × 143 mm with 29 parts on 19 nets, routed with 137 tracks and 13 vias.
It is built around the CR2032 and LL4148. Its parts include 13 diodes, 6 resistors, 3 capacitors, 1 IC and 1 connector. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Plant water indicator
octoplant helps you keep your plant hydrated. Using 12 LEDs it shows the current soil moisture level and allows you to set the water point so you can easily see how far off you are from the moisture level at which you normally water.
It's designed around an attiny824. A custom PCB combines it along with 12 LEDs, a wide trace that acts as a capacitive moisture sensor, a button, and a cr2032 battery (holder).
Simply press the button to light the leds. The soil moisture level is measured and then compared to the calibrated wet and dry points. By holding down the button you can save a moisture level and this led will blink on all further readings (I like to use this to save the level of moisture I usually water at).
Built with:
- Arduino (TinyMega core)
- kicad
- platform io

Questions
How big is the Octoplant PCB?
It measures 15.2 × 143 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Octoplant use?
29 parts, built around the CR2032 and LL4148. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Octoplant KiCad files?
From the harry48225/octoplant repository on GitHub, at the commit this page was made from: the board is pcb/octoplant.kicad_pcb and its schematic pcb/octoplant.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Octoplant design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
