Measure distance using JSN SR-04T Waterproof ultrasound sensor with Arduino and LCD i2c

Hi, welcome to this tutorial, where we interface the JSN SR-04T with Arduino uno board and LCD i2c screen, measure distance in both cm and inches and display it on the serial monitor then an LCD i²c screen, then trying it underwater to measure distance, if you have any problem contact my FB page or write a comment below. Hope you like it.

Sound travel in air at the speed of about 330m/s, and about 4.4 times faster in water (1450m/s)
That means the actual min/max measure distance in water is also 4.4 times in air
20x4.4=88cm is the minimum hardware limit

I NEED A SENSOR which gives 50 data every second. And it must measure the distance fastly (like 20 milliseconds) And it will measure long-range (like 4-5 meters). Do you have any suggestions?

I really enjoyed the video. I'm going to experiment whether I can measure water and ice using the same sensor.
I am worried because the value is minute.

I connnected the board JSN SR04-T to Arduino with cables (= 4 m), I got problem sensor didn't work well, parameters are floating. Please give me some advice. Thanks!

Please is there an ultrasonic sensor that works underwater and measure distances ?

[haziqahazmi]

how about JSN SR20 ? its same for the working principle ?

[burakdinc]

Hi, Thanks for sharing. Did u try over 90 cm in underwater this sensor?

[mahmuddemirok]

Thank you for the video. I HAVE A QUESTİON: Is it sensitive in far? For example, can ı measure the 4 meters outside? I am doing an autonomous car. It will be big and it will travel outside on a road which between barriers. So the car will measure the distance between the barriers and the car. It must measure at least four meters. Do you have any advice for me about which sensor ı should use?
I need to take responses fastly (<20 milliseconds)
Thank you.

I HAVE A QUESTİON ; can i use ultrasonic for depth of cracks

Hi, What sensor can detect the water or diesel "surface"? I want to build a tank level sender in a diesel tank that is 150cm deep. Any suggestions as which sensor would pick up the diesel surface? Thanks

I tried my best but my this sensor did not give correct reading. But with the same software HR04 simple worked well .Please help me

Could you export underwater images of surfaces on a PC screen?

[FuchsHorst]

the waterproof module shown in this video has a minimal distance of 20cm which can be a problem in smaller tanks or other tight conditions.

[muhammadzakwan]

hii... can it measure the distance in oil ?

[anjeel]

Can you kindly make video showing how to use two of Waterproof Ultrasonic Sensor Modules JSN-SR04T-2.0 + Blynk App, to read the water level in "two tanks" togeher and derive the quantity of water in each.  Using this activate a relay to pump water from one tank to another.  It will be great if you can also include a cheap 16x4 or Nokia display.Thanks,

[Im-HP]

There is a transformer or coil with adjuster on it, what is that for?

[MARUTI]

Thanks for the video,
Can you tell any sensor which can sense the water depth .
It should be floating,
I want the distance from the surface of water to bottom.,
A Project of sedimentation.

Thanks for sharing
It looks good.
May I know where can I buy this sensor?

[mapez]

can i have the fritzing file for jsn-sr04t? thank you in advance

[batuhantr]

Is it possible to detect objects under water with this sensor ? For between 20-30 centimeters
