Analog Soil Moisture Sensors allow you to determine how dry soil is and then trigger an event such an LED turning , or a water pump being turned on.
Note: Give the sensor a few minutes to stabilize its readings.
Functional Parts in the Project:
Arduino Uno - store.arduino.cc/usa/arduino-...
560 Piece Jumper Wire Kit - amzn.to/2MsCLjL
Soil Moisture Sensor - amzn.to/2jEDyjQ - Věda a technologie
16:14 - The problem with these (especially the cheap Chinese ones, e.g., from eBay) is that they degrade and die after a while. It's electrolysis, so the metals will corrode. If you want to avoid replacing them all the time, you can use the kind that's covered silicone which read capacitance rather than resistance.
Came to write exactly same comment
Well, the main problem why they degrade is, people are reading values all the time. The solution is, read the value once per 30min. Degradation is a lot less a issue.
@@Dextermorga This makes sense
Man!!... I use to watch your vids when I was searching for ethical hacking.
now I find you on Arduino ..... happy days. :)
You truly made my day.
thank you for the amazing year you have dedicated to all of us, making all these amazing vids.
respect broth.
PS: im the guy that looks like you. :)
Thanks you very mutch Sir
i have to use a soil moisture sensor for my project. Can i 'trust' the results of this sensor?
If you had an expensive moisture sensor, could you program an arduino to match its sensitivity? I am trying to see if I can create my own greenhouse controller since even the best ones seem to be falling out of accuracy after some time or so dang expensive just to be unable to control certain aspects I would like to program. If this is something that is possible I would really like to make a smart controller where it will check status of everything in play to more accurately make decisions. I haven't fully thought out how I want thinks to act because I don't know where my limitations are at this point. Any information you'd think is relevant would be greatly appreciated 🙂
Thank you for such video , just to let you know that this kind of sensor get corroded (due to electrolysis),you can use the capacities soil moisture sensor inseatd .
How long this sensor survive in mud, months? Years?
Like he said, if it's constantly running current, then it's constantly electrolysing the moisture and constantly dissolving the metals. With highly wet stuff like mud, it could be be gone weeks, maybe even days. You can do as he suggested and cut the current after the reading, but it's still wet and will still corrode, so you could try the (more expensive) silicone-covered ones that measure capacitance rather than resistance.
never use resistor versions! .. only pcb covered capacitive versions.
