In this project I will be showing you how to create an automated watering system. My system is made for my greenhouse, but you can use the general principle for pretty much everything and everywhere. The system uses LoRa for remote communication, so that I can water my plants even when I am on vacation. But there is also a push button to water the plants manually. The mains ingredients for my system are a big water barrel, a solenoid valve, a water level sensor and a long garden hose 😉 Let’s get started!

    I don't know how much the solar panel(s) generate but wouldn't it have made a bit more sense to use something like a sprinkler up top with a pump to "make it rain"?
    Mainly because when i look at the water flow, most of the water just concentrates around a few places where the water squirts out of the hose.

    one tip do not make the hose holes equal , make them larger on the end and smaller on the begin , this help maintain the pressure equal from one point to the other

    Hay man I am a very big fan thank you for this video. But my idea is this that you can easy use a timer relay modul like FRM01 for your green automation . Its is working great for me.

    I was feeling depressed and then you uploaded a cool DIY video. I love tinkering and your videos are always pleasant to watch. Thank you. I feel better now.

    Now u just need to full automate it by mesure how moist the soil is and the temp inside and then code the moist meter reedings to the water system and then but af small motor on the Window to open when its to hot inside og close if its to cold

    Disappointed by the fact there isn't a sufficient uniform distribution of water throughout the soil surface. How can this issue be addressed, or even resolved? Not even a sprinkler connected directly to the tap under pressure will uniformly distribute the water. Placing more irrigation drip hoses, becomes difficult to work the soil. Perhaps someone can enlighten me with a simple solution, because I can't see it.

    Nice video! They sell irrigation hoses that are porous to allow water to seep out through them and they don't require any holes to be drilled. Perhaps this might also work for you but you might have to do a bit more code to figure out water usage as they are slow.

    I might suggest burying the hose so it's flush with ground level, and using waterproof sheet or weed-control layer on top to better control humidity and reduce evaporation.
    Another tip (apologies if duplicate), try using a raspberry Pi instead of the LoRa. Simple scripts to control timing etc can be changed remotely, plus you can connect a webcam to live-feed or even take time-lapse video of plants growing to make into a little movie afterwards.

    3:15 When you say "placed all the electronics in the enclosure", you mean "throwed all the electronics in the enclosure" XD

    Might want to put a filter on the intake to prevent the pipes from getting clogged, specially if you are going to let the barrel open.

    Nice job, You could install a few cameras to either timelapse the growth of the plants or to monitor things while you are away. I noticed you don't have any soild moisture sensors anywhere, is this because they are mostly all very poor quality or is this something you plan on adding some time in the future?

    I made something simular with ESPhome to be able to connect to my HA automations. It checks for water level and switches between 5 watering circuits. And you can set how long each will run. It was great.

    With 12V and over one ampere of energy use you could at least try to power a little dc pump instead of the solenoid valve, this would also prevent any algea from growing inside of your tank and clogging the holes of your garden hose. But otherwise i liked this project.

    Finally I can control when the people in my basement get water without having to go down there.
