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.
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.
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
Sir, what is the quantity of water tank that you used to fill water in your small project? Will it work in 500ml or 1L after entering your codes??? And what changes will have to be made in the coding please tell.😊
You need to measure the height of the container you're using and a, b, c, d are the 4 levels (heights) stored in the variables, which is where you'll input the value you'll want the leds to light up at. talkingstuff.net/water-level-indicator-ultrasonic/
@@TalkingstuffNetI buyed everything and project is full working I edited codes while seeing your video and some codes are missing on your website that I changed from seeing you videos just have do some code and measure my container and put variable 😊
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.
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.
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
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.
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.
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 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.
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.
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.
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.
