<div>Hello all,</div>
<div><br>
</div>
<div>I'm looking at building a sonar transducer to measure bottom depth for a small ROV project and would like to ask how I should go about pressure-proof/waterproof the system. </div>
<div><br>
</div>
<div>I'm looking at building it with a Arduino Uno Rev 3 microcontroller and a Ultrasonic sensor module.</div>
