Water depth sensor
Geethesh last edited by Geethesh
I want to make a water depth sensor .
I have seen some YouTube videos of water proof ultrasonic sensor ,but it's will not work under water.
Please any one tell me which sensor should I use.
I want to sense it he depth of water.
From surface to the bottom .
The sensor should be on the surface of water

@Geethesh Glad that you are active with makergram. To help with your query please let me clarify whether you want to know the level of the water surface or know how much depth a certain water body is at??

@kowshik1729 I edited my question.

Hi @Geethesh ,
I got a few sensors to measure the depth of water, some of them are listed .

@Geethesh Try using Sharp IR sensor.....it's more effective than normal IR and can measure distances accurately using ir Rays. Try using it.
@salmanfaris thanks for the details
@Ggreeshma-stani Nailed the PCB in terms of the schematic. But you got it a little bad on the layout side. There are some thumb rules while designing a layout of PCB.
Always place the oscillator and it's capacitors(C1, C2) near to the IC. If you have a doubt on this try checking the Arduino boards or any other boards. you will find an SMD chip crystal alongside of the Arduino XTAL pins. If you ask the reason for this that's simple, to avoid noise creeping in. Crystals provide the clock to the entire digital logic inside the IC. So, there should not be any noise in it. If noise is there, obviously you'll have timing issues.
The bypass caps on the voltage regulator must be placed close to the regulator's input and output pins. The reason for this is also pretty simple, bypass caps will filter out noise coming from the power supply and few other reasons too. So, try placing these bypass caps as close as possible to IC.
Apart from these points, the PCB looked good. Great work. Remember that this message is not to discourage you but just to give a suggestion so that you'll improve it in the next design.

@salmanfaris the pressure range that we have to measure is between 5-10 cmH20 (ie almost 0.07 - 0.0.14 psi)
