I'm going to build this thank you. I have to say this is the best explanation that almost addresses my specific problem. Well in fact I might just run with this instead. Only thing is I need to run a 12V 19amp pump. I wasn't able to get it working with either a relay or a mos module unfortunately

Great watering technical solution and good video, but I also try that earlier and after one mount the copper spikes corroded and disappeared :S . I logged the watering numbers and onced the numbers turned to unreal . Maybe try the capacitive type measure spikes (that is coated with paint or hard material coat).

I noticed you provided the code for the moisture sensor on the website. Is there any chance that you can also provide the code for the automatic plant watering system's code as well?

Hi, sorry do you have a link to the tinker cad? iv been trying to see all the bits and names but couldent get to it

@Science.Buddies Жыл бұрын

Sure! The Tinkercad link is here (this was in the written description on our site but not directly in the KZbin description): www.tinkercad.com/things/lo6w80FQ4Hi

I'm sorry, but don't you have those sensor resistance levels backwards? If the resistance is below the threshold then the soil is wet, and vice versa... What am I missing?

@Science.Buddies Ай бұрын

The key part here comes around 5:25 in the video - the sensor outputs a voltage, not a resistance, and this voltage is inversely related to the resistance. You are correct that *lower* resistance means wet soil, but a *higher* voltage means wet soil. So if the analog reading is above the threshold, the soil is "wet."

@Science.Buddies thank you, I see now. My confusion stems from me being an electrician. The way I was looking at it, the moisture sensor isn't outputting a voltage, it's more like a variable resistor, so we're just really measuring the voltage drop across the device and adjusting accordingly.

If you put two resistors in series you can make something called a "voltage divider" - there are tutorials for this on KZbin if you search for them. In this case the soil moisture sensor likely actually consists of two resistors - the resistance between the probes, and an additional fixed resistor on the board that forms a voltage divider. This is a common configuration when using an Arduino with a variable-resistance sensor because it lets you convert resistance (which the Arduino can't measure directly) to voltage (which it can measure). A photoresistor is another good example.

Hi, thanks for making this great video. I would like to build a system like this for around 30-50 plants each requiring their own sensor and water feed. How can I scale your setup? The arduino board you showed only has 6 analog inputs.

Hi - you can look into the Arduino Mega which has more pins, but still might not be enough for your case. We would recommend asking this question on the official Arduino forums where you may get more help.

I just built this it it did not work is there another solution?

If you are a student doing a school science project, you can ask for help in the Ask an Expert forums on our website: www.sciencebuddies.org/science-fair-projects/ask-an-expert-intro. In order to provide help, we will need more details about what isn't working and we'll need to see your code and circuit diagram. Without that information we can't tell you why it isn't working.

may i ask whats the name of the mosfet used in here?

You can use this or something similar: www.amazon.com/gp/product/B07CTF1JVD/

Hello, i also do this project for one of my courses. Can you tell me what transistor should i use? I only have one type at home and its a IRF540N. Thanks :D

@Science.Buddies Жыл бұрын

The IRF540N or any generic N-channel MOSFET should work for this project.

Hello, mine works pretty well but there is one issue. When I try to set the delay time over 30 seconds it doesn’t work properly, any ideas on how to fix this? Mine’s been hooked up to my plant for a few days on 30 second delay but in the long run the sensor won’t last as long so I want to find a fix. Thanks Edit: got it to 60 seconds, had to change the const int

@ObsequiousV4 11 ай бұрын

I notice the LEDs turn on below threshold but the pump doesn't. Is there a bug with tinkercad or is it something with the code or hardware?

@Science.Buddies 11 ай бұрын

Hi - we can help you with this project if you post more details in the Ask an Expert forum on our website: www.sciencebuddies.org/science-fair-projects/ask-an-expert-intro. We will need to see your code and pictures of your circuit to help you debug. Many times problems are just due to a misplaced wire on the breadboard.

you probably need a seperate battery to power your pump (if you mean its happening irl)

May i ask how to add lcd monitor in this? Hope you can answer it.thank you

@Science.Buddies Жыл бұрын

Hi we have many other Arduino tutorials on our channel but unfortunately we do not have one on LCD monitors yet. Stay tuned as we may add one in the future! In the meantime you should be able to find many other Arduino LCD monitor tutorials on KZbin.

Where can i buy this

@sohaibmalik6846 6 ай бұрын

Let's say I created an android app. Now as the soil moisture drops below certain range, I want it to notify me on android app. Can Arduino do something like that, can it be programmed in a way that using some other programming languages we can get the data through it?

@Science.Buddies 6 ай бұрын

Hi - we don't have our own tutorial on it but you can buy Bluetooth modules for Arduino that will let it communicate with a phone. You should be able to find other instructions online!
