I am making the automatic water controller using Arduino and Ultrasonic Distance Sensors. My prototype is almost ready. But I have a doubt that if I put the sensors on lid of the water tanks, water vapours might cause some problem or could damage the sensor after a few months. Or if by some way water touches the lid it might also damage it. So how to prevent it?

Thanks

Simple, by using sealed ultrasonic sensors.

  • \$\begingroup\$ I have unsealed sensors, so how to cover it, using which material? \$\endgroup\$ – Vivek Muthal Nov 18 '15 at 9:28
  • \$\begingroup\$ @VivekMuthal what does the data sheet say about covering the sensor with materials that don't impede ultrasound. If nothing then contact the manufacturer or do experiments with (say) PTFE. \$\endgroup\$ – Andy aka Nov 18 '15 at 11:27
  • \$\begingroup\$ Really. Get rid of the sensors you have, and get sealed ceramic ones. There is no Ultrasonic transparent 'coating' or 'cover' that I can think of to work with whatever you have. \$\endgroup\$ – R Drast Nov 18 '15 at 13:33
