Waterproof Ultrasonic Sensor A02YYUW with Arduino, ESP32, & ESP8266

Very good

👍👍👌👌

Great video! I like the comparison and you do a great job with a tutorial❤❤❤

Can you use this to DIY a "fish finder?" Would the 450cm distance limit change in water? That would not be nearly deep enough. The 60* viewing angle would be really wide, for a fish finder.

If this sensor was used inside of a portable water tank and the tank was placed on ground that was not level, how would that effect the reading?

Great as always 👍👍👍
Thank you

NICE

I am using the code but I am getting an error :"softwareserial does not name a type"
