Do note that these kind of sensors suck due to corrosion: 1) Thus they break after some time 2) The corroded material stuff is partially released into the surrounding environment, which may not be ideal. Instead look for conductive sensors which abuse induction for measurement.
Wow, Mike, We're getting a FLOOD of videos from you suddenly... Srsly, you're confusing the youtube algorithm doing things like this. Pace yourself, man!
Tried this sensor, it worked about exactly as well as I expected it to. It's heavily dependent on the ion content of the water, which depending on your setup, may be something highly variable. Also, as soon as you get it wet, it almost immediately goes up to full output and stays there until it completely dries off. So unless you're constantly there to wipe off the sensor, this isn't going to be very useful for a lot of projects.
I've tried to create a device to empty a container collecting water from air conditioning using this exact sensor. It did not work as expected for the reason you've mentioned. As soon as it gets wet, the value on the analog input goes almost all the way up. If there is any water residue on the sensor it remains that way. So If you just want to know when the sensor gets wet and you're not particularly interested when it dries off, I guess it's okay. But for any other applications I'd recommend using some sort of liquid level sensor with float. Aaaaand I'm having doubts about its long term reliability due to metal threads in contact with water...
Simple trick to solve this is to put tape over all the contacts and just cut out 2 strips at opposite ends. The point is to stop water drops from sitting between contacts. Otherwise its a good module for the price.
This is great. Is it safe if the 5V pin is constantly exposed to moisture/water? Also, how do I know if the water gets below a certain level for deeper water tanks? Thanks for this video :D
This looks like it will do exactly what I want. I have a pool and the 'standard' water level is quite high in relation to the capping, so when it rains heavily I have to be alert to go out and empty water before it overflows. I'm thinking I'll build this and mount it inside the skimmer box so it will alert me when the water gets too high with an alarm buzz - and potentially find a way for it to send an alert to my phone.
Nice video! However, I do have a dumb question Does this effect the quality of the water overtime if you do it for a long time? Would it also be dangerous for a person to drink that water while the sensor is in it?
Yeah, it'll cause corrosion and release material into the water. No idea if it's dangerous, but it's not something I'd want in my drinking water or in a plant I'm going to eat.
How to do the wiring and programming if it connected with solenoid valve. The low level will turn the valve no and the high level will turn the valve nc
This is message for everyone who gets only "MEDIUM" as the highest value. Try to use "val > 220" as high water level. This is because analog can give you value 0 - 255 (1023 / 4).
NOPE you need to write the program to work. Based on the values you read from the water sensor you decide what to do. As in this example is just reporting water lvl with Text only. You can go step further with this example and like limit the daily usage of water like 10litter per day/hour...
Thank you for this video. I don't have a lot of time to figure this stuff out myself right now. (maybe when I retire :)) Have you ever done a weather station with Arduino? I didn't notice one in your videos.
I am new to Arduino and this. I have seen people mention corrosion, is this something that occurs fast or over a long period? Also for determining the values for the sensor to set for low and high, where do we read that at?
There is a problem with your code, a bunch of if/else if isn't really efficient... The true way to do it is to create an array of string with the message to print for each value, and then you just need one line : lcd.println(my_stupid_array[resval]); ^^ More seriously, your video was really nice :)
You're right. All of my sample code is written in such a way to be easy to understand for beginners. Not be efficient. Most of my project code files could be reduced by 75%. I also never include error checking for the same reasons. I don't want to add unnecessary bits that beginners don't need to know yet.
Would be a cool thing for use with aquariums. Knowledgable remove and replace some of their tank's water at regular intervals (for me, it's 25% every week). During the time that the water level is low, I switch off the power strip for the heater and filters to avoid damaging them. Imagine if the switch was completely automated; from your design one just would need to add a 110 volt relay and probably a shield board plus of course tweak the code.
i think the potentiomenter is a requirement. Without it, you can not adjust the contrast, and the characters on the display may not even be visible if the contrast is not perfect. But i could be wrong, maybe its possible without it? but i doubt it
I think a ultrasonic distance sensor might be a suitable option. I can try it tomorrow afternoon, I have some laying around at home. If you're interested let me know!

amazing for my massive fish tank! I travel a lot and it's good to know when the water level is getting close to the unsafe level for the heaters!
How? You can only dip it in a few inches.
@@kraigparadise5770 If the water level gets too low in a fish tank, I'm assuming. So it would only need to be submerged on the top bit.
@@kraigparadise5770 ?? If the water is more than inch low, there's a problem!

use a pressure sensor
Hi .. what sensor would be used to check water level in a water tank?
I would go with an ultrasonic sensor.
Hey how would you add a water pump to this circuit and to the code? Thank you

Hi, These sensors oxidize shortly after use , Is there a way to solve this problem?
Interesting project, but why the cut scene of a couple of frames two people standing in the field at 1:35?
LOL. Final cut pro bug. I must have clicked something accidentally before uploading.
Would be interesting to see an alarm or text notification linked to the water level. Thanks for sharing!
How?
This is exactly what I’m tryna figure out
when I tried it, it just said Water Level High without change, can somebody help me?
@GC Grdn hey did you get a fix?
hey did you get a fix?
how to apply on giant tank ?
Maybe you could place multiple water sensors on different heights of your tank
Anthony Arseneau
Good idea
I didn't know those water sensors produced an analog output, I always thought it was a digital HIGH or LOW.
lol almost all sensors output analog. digital output is basically useless in sensors.
Nice video! However, I do have a dumb question

How would I add a pump to this sensor that will start if level gets to a certain low level?
I am not able to under stand the codes in pc
What is the correct brand name of the sensor?
Hi ! can I know the unit for the analogue value output from this sensor?
Will it oxidase?
great tut, if possible can I modify it to make this in a large water tank thanks
You can do that by putting the sensor at the edge f the water tank Bro
ty
yow
Wouldn't it be yAw?
can i ise this with diesel for fuel level ?
Probably. You'd have to test it. It most definitely would have a different resistance value.
why when i run with the coding, the lcs is still blank??..no word is appeared?
mohamad hilmi same happen with me bro
Hey bro this is awesome but i have a request. Can you draw what the circuit would look like?
can you explain for the condition empty, low, medium, high calculation
can you get a bigger water sensor than what shown in the video, bro
is the sensor suitable to be used in a sea water?
if yes, can a digitizer be used to convert the analog signal to a digital sensor
If the code none problem, why the lcd didn't print out any word?
can this actually works in big tanks, where you widen the low, medium high levels of water?
Absolutely. You'd need to design your own on a PCB.
What is the Name and Model Number for this sensor, so I can search it and buy it
I wanted to ask that can we use map function to keep check on value input coming from sensor?
Hey im just wondering if this would work if i would want to sense spillage on the floor
Does anyone know this detectors mass?
Nice tutorial
Hey does this detect any liquid
This is message for everyone who gets only "MEDIUM" as the highest value. Try to use "val > 220" as high water level. This is because analog can give you value 0 - 255 (1023 / 4).
thank you this video was vert ahffasdful
Cool stuff, can you update the linked to your sensor looks like a copy and paste error you've got duplicates
Whoops! Sorry about that. Done. Here's it is: amzn.to/2HfrlLC
On which app we have to type codes
Arduino app
When I try the water level sensor serial, the serial just come out "water level : empty"
"water level :low"
May I know what the problem
maybe try without the lcd at first just to check what values it gives out than adjust your contraints according to that.
does it work if i dip it in oil ? because im making a project to gather oil in a container...
Probably. But the resistance values will be higher so you'd need to figure out the new scale.
how do i implement these same items in Proteus????????
please ans
Hey, I have a problem. Why is my sensor corroding and producing this light blue material?
Could it be connected to any relay to turn on a pump?
yes but this sensor no work fine its best a magnetic sensor
Hey, can i use it with multiple module at the same time?
Can this work without any programming?
NOPE you need to write the program to work. Based on the values you read from the water sensor you decide what to do. As in this example is just reporting water lvl with Text only. You can go step further with this example and like limit the daily usage of water like 10litter per day/hour...
can it be used for river water level monitoring
Thank you for this video. I don't have a lot of time to figure this stuff out myself right now. (maybe when I retire :)) Have you ever done a weather station with Arduino? I didn't notice one in your videos.
i wanted to create a device that detects the fish feed level and inform it via SMS, how things do i need to procure? thanks, good video btw

Hello, nice video.
I would like to know if there are longer sensors (I need a 15cm one)
Thanks !
Not that I am aware of, but quite honestly I don't think it would be very hard to modify this sensor or just make your own.
@@TheGeekPub Yeah I think I'm gonna go with my own. Thank you!
Are different sizes of the sensor
Good work
what is the measuring unit with water level sensor???
thanks
How to solve Stick up water?

What's up with the creepy single frame at 1:35? Looks like a silhouette of some people. The music is creepy too.
That's the Final Cut default frame. I probably didn't but those two clips all the way together.G
@@TheGeekPub Darn I was hoping I found an Easter egg.
1:35???
Its not working. I am not using a potentiometer. So i am not attatching any pin at that place.
"My car is missing the steering wheel! It won'g turn! Help!" You can't make this stuff up folks.
What it the whole sensor is soaked? will it fry the arduino?
No, but it might fry the components on the sensor.
i want sensor for water level in 50cm deep tank, how to use this sensor ?
you need longer sensor
Can i have your schematic circuit of these project
They're all on my website.
hi, i want to measure the height of the liquid inside a small container, to determine its volume. which sensor is suitable for that? IR proximity?
I think a ultrasonic distance sensor might be a suitable option. I can try it tomorrow afternoon, I have some laying around at home. If you're interested let me know!
@@alexandervanhell7427 I would really appreciate if you could do that thank you very much
how did u guys finish it? I am currently doing this and dont know too which one should I use
Skynet sir......😂
Would this sensor work with other liquids besides water?
Most likely, but would need to be calibrated.
TheGeekPub I’m trying to make a setup for my resin printer to know the level of resin still in the machine.
Niceee
