Nice video I did combine 2 of these sensors for my water tank. One at the low level to start my water pump and the other to stop the pump when the tank is full.
I used the same sensor for measuring the oil (petrol) level for my house central heating. They can work on thicker plastic containers and you can set the sensitivity from their potentiometer
@@KPeyanski i still use it, 2 years later. I have it outside mounted in an electricians box which is attached/glued really close to the outside wall of the tank
Bought the sensor directly after watching this. Exactly what I needed for the project I plan on doing. It's so frustrating how often I must fill the Keurig reservoir. Have the ESP32, have already ordered the pump....the only thing I was missing was a good water level detection method The idea is to have a much larger supply of water underneath the shelf the Keurig sits on. Will just use the pump to refill the Keurig whenever the reservoir gets low. Was considering an ultrasonic sensor and then drilling holes into the lid. But now I won't have to drill anything and it'll look so much better! Thanks so much dude please keep these esp tutorials coming!
@@KPeyanski Not a stupid question at all! It's an approach for growing plants (herbs for us) in water instead of soil. The water tank needs to be refilled every few days and we often forget so it's good to have Home Assistant notifications.
Awesome!! I was just looking for a water fill sensor for my new bathtub (to stop water flow via electric valve when bathtub is filled to a certain level). Love it!
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.
I have a rain barrel for which I want to be able to see in HA if it's below 50% and 25% water level. Is it possible to add 2 such XKC Y25 sensors to one ESP board? If so, which pins would I need to use on the board to solder the sensor cables and what would I need to modify when flashing the firmware? I'm still "dipping my toe" into this whole ESP32 things and trying to find a start...
Thank u very much i was already was looking to this sensor for couple years now but i couldn't figure out how to use it in my house, i am not that smart with these things, so had let it go, but now i will try it
Hey Mister. Great video 🙂 But do you know if it's possible to disable the light diode on the xkc? Now it turns on (on stays on) when it detects liquid... Big thanks from Norway 😎
Hello, I have a water dispenser connected to a 5L jug and with what you shared, I can send a notification when the water is running low. Thank you for sharing knowledge!
Another excellent tutorial! I've tried to add a second sensor on another pin and I got the error message "Only GPIO16 supports pulldown." Did a bit of googling and I'm still a bit lost: my understanding is there's an internal resistor that gpio16 can use, but no other pins - does that mean I can only get 1 sensor per D1 mini? Or can I add my own resistor, if so what value would I need? Ultimately I'm wanting to fit 6 of these on 1 micro controller, should I be looking at another ESP board? will that be easier? many thanks for all your work mate!
great video! that's exactly what I was looking for, for my camper's grey water tank, thanks a lot. I'm just wondering how many sensors I can connect to a single ESP32? 3 or 4 would be perfect for me.
You can have 3 or 4 sensors on one esp32. My initial idea was exactly this - to use 3 sensors on one esp32 for the grey waters on my camper, but I still can't find enough time to make it happen. Hopefully this summer I will make it.
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!
Just get the PNP sensor if you wish to connect it the same way as me and to use the same ESPHome code. Otherwise you will have to experiment / read and figure it out by yourself
Excelente trabajo saludos desde Colombia, yo hace como 7 meses lo hice con el mismo sensor y unos sensores sonoff de puertas o ventanas, funciona pero definitivamente mucho más práctico y económico usar esphome, gracias 👍🏼
You could just use a 12V power supply, a voltage step down converter, a dor sensor (zigbee for example) and this sensor and be done with it :) no need to program anything, just solder and do the same scripting as a door sensor in the home assistant :) But of course, when you need more complex stuff, you can do it with an esp / shelly uni. i will probably use a shelly uni to measure aquarium temperature, water level with this sensor and also control a water pump for auto water top-off. With the shelly uni, as it also works directly with, I believe, 12 to 36 volts, if I a power supply of 12 i don't even need a voltage step down converter.
What's the difference between PNP and NPN? Can you use them NPN here instead of PNP?Also how can I add a second sensor ( which pin on the d1)? Great tutorial.
Nice. Might add one to my aquarium. What do you think would be a good solution to affix it to the aquarium outside glass? Would double sided tape work or would that throw off the sensor?
Great video as always.. I didn't realise such a sensor existed. Did you get the code for adding a second XKC Y25 sensors to a single wemos d1 mini. that way you could monitor clean,and grey water levels with the same wemos.
In theory yes, as the max humidity stated by the vendor is 100% which I understood as inside liquid :) But I guess this have to be tested and there is a small risk to damage the sensor.
#LiquidSensorOwned, just a quick question I am using this for my Aquarium to know when to add water , how can I get an SMS instead of notification? Thank you!!!
Great work & Congrats. For SMS-es you have to add such notification integration in HA. I can suggest to check this video of mine - th-cam.com/video/OECAjHMwLro/w-d-xo.html If I remember correctly notify.events support SMS-es along with dozen of other messengers

Hi Kiril, I’d like to embark on the ESPHome trip sometime soon, but I have a big question I hope you’ll be able to answer to: is it possible to connect sensors to an ESP32 and use their output to modify the behaviour of the ESP32, without passing from Home Assistant? To be more specific, I’d like to connect a led and a photoresistor to an ESP32, and I’d like to internaly dim the led accordingly to the photoresiststor output, without constantly pulling from Home Assistant the photoresistor output. Is this possible? Thanks for your time.
@@KPeyanski may I suggest you a video on this topic? Documentation isn't super clear, I cannot find any resource online. I ended up coding it in MQTT and it's working, but I'd prefer to switch to ESPHome. Thanks!
Please don't stop with these ESP tutorials! It's fun to make own sensors :D
Do not worry, I won't! It is fun to me as well :)
Using these many different types of cheap sensors from China is so much fun and indeed very useful. Keep up the good work!

@@KPeyanski thanks, how can I add another second sensor? Which pin?
how can i connect a ky-016 led to see green and red status?
ESP32 has touch pins, we can turn them into sensors with liquid lavel
Can you share more info about that please?
