In this video, we're going to cover how to use the water level sensor with the Arduino.
The water level sensor will help you easily detect the presence of water and a relative idea of its depth.

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!

@@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.

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.

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.

@TV4Fun2 4 жыл бұрын

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.

@TheGeekPub 4 жыл бұрын

It's highly dependent on the mineral content in your water.

@ratamatum 3 жыл бұрын

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...

@ivgnes 2 жыл бұрын

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.

@davidwayneprins 5 жыл бұрын

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.

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%.
