Raspberry Pi Plant Watering (& Time Lapse)

Raspberry Pi Zero plant watering system using a resistive moisture sensor, solenoid valve and relay HAT. And there’s also a camera for recording a time lapse movie of the plants growing!

You can download the code used in the video from this page:

My previous “Raspberry Pi Battery Power” video is here:

And the video where I first use the relay HAT is here:

The moisture sensor I used is here:

The FPD-270A solenoid valve I used is here:

But the price has increased, and a cheaper equivalent is here:

And an alternative on Amazon.com is here: https://amzn.to/3xKxgjF (affiliate link).

Note that different FPD-270A valves have different diameter inlets and outlets, so make sure you know what you are getting and what pipe will be required! :)

The two-relay Pi Zero relay HAT I showed in the video is here:

The three-relay HAT I actually used is no longer available in the UK, but is listed on Amazon.com here: https://amzn.to/2TgHKrZ (affiliate link).
