Here are the details of my Automated Herb Plant Watering System: Link
If anyone has tips on small pumps, I would welcome guidance. This little 5v pump is fun and meets my small needs, but not sure it could service a dozen plants. So, I’m searching for a larger pump, likely have to go for something 12v as well.
My kids said the same thing! Yes, definitely another sensor + pump + relay would allow for those measurements to distribute water to plants that need more water, etc.
Fortunately with open GPIO pins on d1-mini, this means I could easily add more sensors and relays to control the pump.
Looking to duplicate this to support about 10 plants, so may walk down the multi-pump approach.
BTW, see you are from New Zealand – awesome place/people. Greetings from Munich.
