Woah. This is awesome! I travel for work and keeping my plants happy has been vicious trial and error with passive auto watering stakes. I've been looking for a convenient sensor package so I don't have to muck around with wires. Jackpot! There are many raspberry pi projects on reddit for the "microgrowery" community... I recommend having a search. I plan to set up an indoor tomato and herb garden using these methods. For solenoids, I advise some methods like [1] so that you can connect a cheap and daisy-chainable relay board like [2] via SPI. Then you can control anything. If you don't want to get down into the 5v to 3.3v mumbo jumbo, it may be easiest to connect an arduino or clone via USB to the raspberry pi. There are bazillions of documented ways to drive relays with an arduino. [1]: https://www.tansi.org/rp/interfacing5v.html [2]: https://www.ebay.com/itm/SPI-breakout-board-with-6-relays-fo... |
