I am so happy you have kept up with this concept. This is sure less expensive, smaller and more useful than that packaged sensor we found earlier. Do you ever sleep, or when do you get the time to do all these things? This is outstanding. Thank you again Mr. Soatmon
Very instructive video. Thanks! Can you create a video tutorial on how to connect this to a 24vdc water pump? I'm new to this concept and don't know how to hook it up
Great video, I was looking to use this sensor so that an alarm goes off when the liquid in the car's coolant tank drops, but I didn't want to put in a signal inverter. With your video it is already clear to me that the "M" cable already invert signal. Thank you so much.
Brilliant video, thanks for taking the time. I have a 10m run in my motorhome to the tank and would like to have a warning light coming up. Do you remember the voltage output. I’m asking to buy a lamp which would suite. Thanks again
ohms law I*R=V. You need to know voltage of led. Then calculate resistance to limit current to 20 ma. Example led = 3.0v. Supply = 12v. 12v-3v =9v drop across resistor at 20 ma. .02a*R=9v solve for R =9v/.02a = 450 ohm
Hi Soat man Thank you for bringing the product in a video. I have a specific question. As you said, the sensor will detect plastic or non-conductive. What is the principle of this sensor and whether it will detect opaque (gray pipe) materials?
is it possible to increase the range of the sensor? The plastic tank is double-walled and the gap is too much for the sensor to detect the water so I am thinking if it is possible to increase the detection range.
Please, could you help me once again? I bought a XKC-Y25-V sensor. This sensor has the following wires: Brown (Vcc), Black (Mode), Blue (GND) and Yellow (Output). When black wire has a HIGH level the yellow wire has the same value of voltage Vcc (Brown wire). In my project Vcc (Brown wire) is +9 V so the yellow wire will deliver +9 V if the black wire has a HIGH level. DOUBT 1: What exactly means HIGH level at black wire (Mode)? HIGH level means 3,3 V to 5,0 V or It can be 5 V to 24 V? DOUBT 2: Can I connect +9 V at brown wire (Vcc) and black wire (mode) simultaneously? Thank you very much for your attention!
HIGH means current and LOW level means ground.. u can connect a led for example with arduino and send HIGH value then led will turn on, and LOW (led will turn off)..
I liked your video!! I need to monitor the water level in my home's water tank and I have 2 questions. Please, help me. FIRST QUESTION: Which sensor to use, as I noticed that there are several models (XKC-Y25-V, XKC-Y25-NPN, XKC-Y25-PNP and XKC-Y25-RS485). What is the difference between model V and model PNP? SECOND QUESTION: The distance between this sensor and the panel where the circuit will be (Arduino, buzzer, LCD, etc.) is 15 meters. Will I have losses with this distance? Do I need to install a special cable? THANK YOU SO MUCH!
Hello! I just found a similar fluid level sensor that works with an Arduino control board. From the looks of this in your video, this one will illuminute an LED without need of the Arduino, is that correct? (total newbie here). I would like to use 3 of these to let me know when a difficult-to-access jug is getting full and needing to be emptied. GREEN LED = Jug is less than half full; YELLOW LED = Jug is half full; and RED LED = Jug is nearly full and needs to be emptied soon. Can I do all of that with just 3 of these an no Arduino? Thanks so much!
I'm sorry I don't, I have very little experience with it. Follow the link and you should be able to get more info if you search. Good luck with your project.

Thank you. Please: Is that a PNP sensor or a NPN ? Does it matter ? How does the sensor react to proximity to the water in the jar ? Meaning: if the sensor were placed on the lid how close would the fluid have to come up to trigger the sensor ?
There is a link in the description that will give you more information. It is a NPN. The fluid has to be very close, it would not register from the lid.
😂😂😂 good question.. i think the led is damaged.. do not connect anode of a led directly to vcc, output is an analog output, is sending voltage.. for tha common led a 220 ohms resistence is necessary
@@jordh2051 220ohm resister is used to lower the current value , so that led does not get damages/burst , have to see the datasheet what exactly is the output , should give fix value , from the video it sesems its giving some sort of periodic signal , but the led embedded on the sensor only responds when it is in contact with the water , i once baught this sensor , but was faulty and wasent giving any output
@@HaiderAli-nm1oh yes 220ohms is used to lower current value on common leds.. i bought the NPN model, maybe he bought another model thats why the led blinks?.. i dont know but to blink the led the output need to be taken from a microcontroller (arduino or esp32) etc.. and then readAnalog value.. thats one way to see the led blink.. but in this case i dont know why is blinking.. its weird.. or maybe he bought another model and the output is analog by default i dont know..
@@HaiderAli-nm1oh did u check the sensivility configuration in your sensor?.. mine wasnt giving output.. i opened it up and change the sensivility by moving the internal screw to the left and its solved.
@@jordh2051correct , as u mentioned , one way is to blink the led is to provide some kind of a digital signal with some certain frequencey of a square wave with 5v max value and 0 as min (ground ) , hmm have to investigate this sensor once more in detail via experimentation and data sheet
So if I understand correctly, if you wanted to maintain a specific water level you'd need one sensor for "low" to trigger a relay to kick the pump on and then another sensor to detect "full" which would be used to unlatch the relay and stop the pump?

I'm going to test 3-4 of these for an RV water tank level meter.
I hope it works out for you.
Can work in car radiator filler (hot water) ?

Would also works if I put my hand in front?
Can it be used as a rain sensor on a windshield?
I would like to check the oil level.
Can you help
Thank You!

Not that I know of.
What if the tank is wet? So if its raining does the pump start?

I would think so.
Can you provide that fluid sensor info i needed that...
@@kunalsonne5 I ended up buying this one: www.amazon.com/dp/B07FC5RGC7
Or you use the other contact of the relay and yu don't need the black?
How can I get the code please share with me
Thank you! Very helpful
You're welcome!
Is this also works on distilled water? I want these kind of device to make sure there is no harmful contaminants on the drinking water.
I think if the tank is clear it could detect perfectly. I plan to use it to monitor the tank on my coffee machine.
can you use a Gravity: Digital Water/Liquid Level Sensor for Arduino with a Non-Contact Liquid Level Controller 12V Water Level Switch Sensor bord
Does this work for lpg
I doubt it as the container can't be conductive like steel.
Hi, can i use this sensor with PLC ?
Hi. excellent stuff. do you have the resistor connection diagram with the leds? and would you also know what is the capacity of the resistor used?
I'm sorry I don't, I have very little experience with it. Follow the link and you should be able to get more info if you search. Good luck with your project.

Does it with stainless water tank? I want to have water level indicator for my apartment.
It will not work on a conductive container so it will not work on stainless.
Great little tutorial 👍🏻 How close to the water does the sensor need to be?
It needs to be on the container.
@@SoatMon Thanks 👍🏻

If it's reversible as you demonstrated, does it matter if it's NPN or PNP? 🤔
Very interesting. In a different time this technology would have gotten you burned as a witch. Thanks for posting.
Thanks Mike! I love your sense of humor!

Quick question anybody knows how this behaves if there is dripping water on the jar?
Can this be used for an hydraulic tank ?
I would think so but they tank has to be plastic or non-conductive. It won't work on metal or rubber.
Does it work on any tank material, steel, or black plastic
Plastic yes, not on anything conductive like metal, it also did not work on rubber.
@@SoatMon So it will work even on plastic reservoirs that are opaque?
@@arpinchock Late response, but yes, I have tested it on PVC piping and it works
Will this sensor work on 20mm glass tube?
I don't have first hand experience but I think it would.
So if I understand correctly, if you wanted to maintain a specific water level you'd need one sensor for "low" to trigger a relay to kick the pump on and then another sensor to detect "full" which would be used to unlatch the relay and stop the pump?
That would be correct if you want any kind of distance between the high and low point.
when there is no water, is it possible to emit an audible warning through a smartphone application?
Probably but I don't know. I didn't need that application.
What kind of magic is inside this sensor??
LOL If I remember correctly I think it works off of some kind of capacitance.
