- In an earlier video I had put together a tank water level Indicator using an Arduino. The video has been well received, but one recurring question I get is how to use an ultrasonic sensor instead of the water level sensor. Well, let's do just that in this video.

Thank you for this video and for explaining code very well. Can you please make a video of same using LCD display. It will really helpful.
Nicely done!! Now to figure out how to get it installed on top my water tank and keep humidity out.
3d printed a case for the ultrasonic sensor and except for the sensor transceiver the entire PCB can be encased in silicone. Using a long wire you can have the circuit within the house to view the level, only the sensor stays within the tank.
You can use clear nail polish for waterproofing.
Nice and informative video thank you I will do this to my project
Great tutorial, thank you!
I would like to use this in water, yet....I'm confused by what you said at the end about 9:30.
"If you would like to use it with your water tank, you will need to place it in a protective housing". |
Given this is sonar, would not the echos bounce off the protective housing (instead of the water level), giving reading of protective housing?
If you can elaborate, that would be appreciated!
You will need to place the sensor in a protective housing but the sensor area should be open to be able to transmit and receive the signals. The sensor by itself is not waterproof and will be damaged if submerged in water which includes splashing water too. So to protect the components I suggested 3d printing a housing to protect the sensor to a limit. For example www.yeggi.com/q/ultrasonic+sensor+case/
@@TalkingstuffNet that's fantastic. thank you very much. I find myself currently trying to start designing 3D stuff with FreeCad, and I'm having a little difficulty. Is there any resource or application you would suggest for Windows and a complete novice to 3D printing? Cheers
Can you specify how accurate the water level readings are? in millimeters
Thank you . Great project. Don't we need current limiting resistors in series with the LED's?
We do, as i was setting this up temporarily i didnt use them. But I did mention it in the video. I didn't have low value resistors to add to the circuit.
this video is very educational and its very nice i lov eyour vids number 1
Glad you liked the video, thank you for watching. 🙂
@@TalkingstuffNet thx alot my my favourite youtuber
how can i make the water level work my code is perfect and everything i was wondering what i have not checked
Check the serial monitor to see what values you're getting. As per those values change the code.
Hi, I like your video so much. Can you do a tutorial on ultrasonic water level indicators with a 5v water pump? When the water is low the water pump will start.
Hi, thank you for watching my videos 😁, I will try making one.
Hi Vinayak. I liked the video. Can I use waterproof Ultrasonic Sensor JNR-SR04M instead of HC-SR04. Will there be any change in the code if I use JNR-SR04M.
Thank you
You will have to anyway calibrate the values in the code as per what's being returned by the sensor. I feel the rest of the code should be relatively the same.
Good one
Hi vinayak thanks for this video. One thing i would like to ask is how long can the cable be? Because i am planning to do this with 2 Ultrasonic sensor; one for the top tank and one for the bottom tank (for dry run protection). So the total distance comes to around 80 metres ( top tank and motor are at diagonal corners of the house) 🙄.
I haven't tried installing it in my tank, I'm using a pre-built soltution now and they provide a 100 metre cable with their plug. It works well, only concern I have is the power to the sensor at that distance when we make a custom solution. In an earlier water level sensor video I had used a 50 yard ethernet cable to power the water sensor and it worked.
@@TalkingstuffNet any link to the pre built controller set that you are using?
I'm using tankbolt by Oakter

@@TalkingstuffNet its great. Just one thing. It doesnt have sensor to check lower tank level. If the motor is connected to a well then this is fine, but i have a tank which stores municipality water which sometimes used out when municipality stops water for 3, 4 days due to some maintenance.
The product has dry run protection but maybe that is just checking if level is changing after motor turns on; if no change means no water. But in this case pump will get damaged over time plus we will need to prime the pump manually the next time. 🙄
Product is currently available only in tata cliq now @3990.
It has dry run protection, if the tank level doesn't increase for a certain time period it stops automatically. But it can't monitor the lower tank. I liked this because of the app and Alexa control. There are other options available with both upper and lower tank sensors but no automation or app is present.
hi sir, what if the results of the data are calibrated from ml to cm so that they can be implemented on IOT
You can rewrite the functions to provide the appropriate units and use the output to trigger other devices. We already have inches and centimeters.
Wow..nice
Thank you for watching 😊
Hello Sir. Can we use float sensors instead of ultra sonic sensor- because ultra sonic sensor is not recommended for long term usage. How to rewrite the code for float sensors.
You have generally an on and off state only , you will not get granular levels but you will know when its on so you can play an alarm sound when the tank is full.
Can we apply this ultrasonic sensor to a bigger water tank, like 1 ton tank? If we can, is it enough to use only one sensor?
I've not tried the circuit with a bigger tank, but I did purchase a readymade solution and I'm using it with a 1500 litre tank. Looks like they're using a similar sensor.
@@TalkingstuffNet Which readymade solution did you use?
I'm using the oakter tankbolt at present
th-cam.com/video/cbIdgWi1uBE/w-d-xo.html
Will the output be fluctuating when connected to pump cause in the experiment the leds are blinking on increasing the water level, could it be solved by increasing the pulse intrervell time
It keeps fluctuating between the LEDs as the water has to stabilize and because it's still moving while being poured it triggers multiple LEDs.
@@TalkingstuffNet thanks for replay, one more question will it make the pump to fluctuate when connected
It will not as it's connected separately.
When I installed it the sensor output is unstable ,it keeps fluctuating. This happens only in the tank ,it works fine rest of the time
Tanks have a resonance frequency it might caused a problem.
Hey is there a way i can make the hcsr04(ultrasonic sensor) waterproof?
Maybe make a case for it and submerge the main circuit in glue. But the front sensor is still not waterproof and it needs to be open to send and receive signals so it's not going to be totally waterproof.
Can we use lcd screen instead of led to indicate the level of water
Yes you can, but you will need to rewrite the code as required for the LCD screen .
An also i need to add a buzzer to arduino so in which pin do we need to connect it an lcd display connection pin also
I have the code in python for raspberry pi but its very costly how can i implement the same code of pi in ardunio
I have provided the code on my website for the Arduino. But without a LCD screen. There should be tutorials available where you would show the percentage value on the LCD as per the level of water.
Not getting the proper output after connecting,automatically led light gets on and only one led is getting on...can i get the instructions of what to do?
You will need to calculate the height and set the variables accordingly. Also try changing the code to see if you change to a different led does it light up instead.
Does this also on/off the motor automatically?
This would only display the water level in the tank, but you can write code to control a motor when it reaches 100%.
sir this project circuit diagram and result pls tell
You can find the link in the description, the code is available on my website.
Sir can you send program to me pls iam doing project on it can you help me
It is available on talkingstuff.net, the link to the program is in the description of the video I shared with instructions.
Sir..can i get your coding please..
Hi, link is available in the description which opens on my website talkingstuff.net
