Plastic dip the circuit side

Make it from plastic and find a way to pump up the amplitude of the reader by 999quintillion x or more

>>14701760
i stick my tongue in the dirt

>>14701760
Yes, as there are industrial grade sensors that last for years

>>14701760
My first suggestion is stop being an incel trying to manage plants like it's a video game.
My other suggestion is stop expecting the cheapest chinese electronics to be made of corrosive resistant materials.

>>14701799
You sound like a faggot
Imagine being such a petty piece of shit that you care about someone enjoying automation as a hobby (if he's not doing it as a business)
Are you a boomer? Or just a cunt?

>>14701786
pretty much this, use your finger and intuition. It's pretty onions boy to need a senor lol. What you're growing does not need hyper specificity lol

>>14701807
>onions
SINCE WHEN CAN I NOT SAY SO Y BO Y. lol

I step on flowers. I force trees into dwarfism. I shit in the woods. Your pathetic plants are nothing to me, hippies. They are my slaves.

>>14701760
Mechanical, Soulless machines cannot mix with Nature, so no, it's like trying to replace flesh with metal, it simply doesn't work

>>14701807
finger works fine until you have a layer of rocks or something else to retain moisture in the soil

>>14701806
enjoying automation as a hobby =/= an incel trying to manage plants like it's a video game.

>>14701817
>I shit in the woods.
Thanks.
t. plants.

>>14701825
just water more nigga

>>14701860
doesn't work on all plants. some get root rot. you see... the initial question i asked does have warrant

>>14701799
I can tell you play a lot of video games. Automation is important if you are actually trying to feed people instead of being a lazy dependent moocher.

>>14701817
You are only alive because of plants...you know that right?

>>14701825
Or thousands of plants.

>>14701818
Go shit in a lake, hippie.

>>14701867
People who are "actually trying to feed people" don't grow shit indoors with sensors.

>>14701873
plant nurseries have 100x the plants you will ever have and don't follow "HACK YOUR PLANT" guides on youtube.

>>14701863
without rocks it evaporates faster retard.

>>14701818
ok please say that next time you go to the shop and buy your kilo of potatoes for 70p

How difficult is it to grow plants indoors? I have been wanting to get into gardening/farming, but don't have a garden. I don't intend or think I can go self-sustaining (obviously), I kind of just want to experiment, but don't want to be too wasteful.

>>14701895
What are your expectations?. You literally just need to put a sliced tomato or whatever in a bucket of damp soil next to a window/lamp

>>14701877
You're fucking retarded if you believe those places don't have automation in place.

>>14701799
>My first suggestion is stop being an incel trying to manage plants like it's a video game.
Why don't you shut your mouth urbanoid scum? Be glad you still have food to eat

>>14701760
scientists don't care about their negative impacts on the environment or on others' lives, they only care about getting money for themselves

>>14702020
Sometimes there's sprinklers and lights that run on a timer. Sometimes not.
If you wanna get real fancy you can have a secondary timer that activates when it's really hot. That's about it.
Go to a nursery yourself and ask the staff if you don't believe me incel. They're usually happy to talk a bit.

>>14702037
>the guy who wants to stay indoors and play with computers calls me "urbanoid"
what?

>>14702056
Based science hater. 170+ IQ is to realize that science is not making life better.

>>14702069
>the guy who wants to stay indoors and play with computers calls me "urbanoid"
>what?
urbanoid is a mentality.

i respect much more a basement dweller living in pic who managed to create an entire ecosystem inside his house than a green faggot who uses AC and complaings about bugs biting him

>>14702076
you really need to work on your reading comprehension. Then you don't have to be triggered by things nobody said.

>>14702076
>guy grows some tomatoes
>omg you created an entire ecosystem in your house
this is the most urbanoid comment ever lmao

>>14702087
>guy grows some tomatoes
who said anything about only tomatoes?

>not OP
>not even controlled by arduinos.
Probably the dumbest post itt so far.

>>14702098
reducing plants to some sort of art installation is peak urbanoid. Just change your phone background and save the money zoomer.

>>14702098
>>14702180
If you live in a concrete structure, own a computer and have an internet connection, you are an urbanoid of the lowest rank. Case closed. :^)

>>14701817
you are the hippy here. I bet you only shit in the wood because sewage treatment plants are one of the leading sources of methane gas, while in the woods your shit will bind CO2 as humus.
It is optimal to dispose as much of our organic waste as possible in nature.

>>14701895
Start with microgreens, herbs, or cut-and-come-again crops like watercress, scallions, lettuce, ect.

>>14701760
Try painting the copper with conductive paint to protect it. Typically the issue with those is corrosion of the electrodes

>>14701760
no not really. you should just gold plate the plates. soil moisture sensors work by measuring resistance.

>>14701760
it makes more sense to know how much water to add in well controlled soil than to measure "moisture"

>>14701807
I want to autistically tabulate minute-by-minute moisture levels in a csv file so I can look at the pretty graphs

>>14701760
Yes. Gold plated electrodes are corosion resistant.
Alternative 2 is to measure the weight, just compensate for added mass as the plant grows.

>>14701760
ctrl+f "capaci" yields nothing, so I'm gonna say it: Capacitive sensors.
Also, do they last 8 months if you constantly use them or if you apply voltage once every 10 minutes? It corrodes much faster if your code is stupid.

>>14702056
>scientists are to blame that subhumans throw their plastic masks in the environment instead of the trash.

Just get a pot with a properly sized saucer (most shops sell too little saucers nowadays) and waterinto the saucer.

>>14701760
:Start
Dip sensor for a minute
Read sensor
Take out sensor (via gear motor control)
Brush it with air compressor
Wait few hours
Goto :Start

The trick is to not keep the instrument dipped inside all the time, but still getting relatively accurate hourly information.

>>14704034
>spending 120€ to make your shitty 9€ ebay sensor last longer
retard
>will create a sensor sized hole in the soil so it can't read anymore
double retard.

>>14704570
OP didn't say he only wants to spend X.

OP only wants things to last longer

>>14704580
Then he can buy 10x more expensive military grade sensors and still save money, space and effort compared to your retarded idea

>>14704609
There's no "save money" question.

That's your own poorfag thinking.

>>14701760
"impervious" no. But you can use higher quality sensors made out of stainless steel.

>>14704733

>>14704791
>military grade sensors
For soil moisture measurements in a flower pot?? I had no idea Pentagon was planning wars inside flower pots.

>>14701760
why don't you use an analog system using two pieces of rebar.

>>14704854
used for landmines to arm when in soil.

>>14704854
All it does is measure resistance between electrodes. They're called soil sensors on ebay because that's what most people buying them on ebay use them for

>>14703792
OP's pic probably is capacitive. Two metal strips on a board can work too: Esp32 and similar have capacitive touch peripherals so you don't need the $5 sensor PCB that converts capacitance into voltage.

>>14701760
I assume sensor works bu measuring soil electrical conductivity/resistance?
Then just make electrodes out of stainless steel or carbon
It can't be that hard
