Waterproof Ultrasonic Distance Sensors - JSN-SR04T & A02YYUW 💧☔

Today we will take a look at the JSN-SR04T and A02YYUW Waterproof Ultrasonic Distance Sensors. We will see how they work outside, and we’ll even test to see if they work underwater (spoiler alert - they won’t!). Article with code: https://dronebotworkshop.com/waterpro...

After all, it’s simple to use, it works pretty well, and it is very inexpensive. But while the HC-SR04 is a great sensor for indoor use, it isn’t really suitable for use outdoors. It is susceptible to dirt, it’s relatively fragile and, most importantly, it isn’t waterproof. So today I’ll be examining a couple of ultrasonic distance sensors that are fully waterproof. They also are more advanced than the HC-SR04, as they are both capable of calculating the distance measurement by themselves, without the aid of a microcontroller or microcomputer. The JSN-SR04T is an interesting sensor for a number of reasons. First, it uses a single transducer, instead of a separate transmit and receive transducer. Second, the transducer is attached to the main circuit board with a 2-meter cable, allowing you to mount the waterproof sensor remote from the non-waterproof board. And third, it actually has six modes of operation. The A02YYUW looks a bit like a large, rubberized HC-SR-04 in that it has a separate receive and transmit transducer. But that’s where the resemblance ends. This is a smart sensor that outputs serial data, and it can run on 3.3 or 5 volts. We’ll hook up both sensors to an Arduino Uno and write some simple code to use them. And, as the JSN-SR04 and A02YYUW both use the same format of serial data, we can even reuse the same sketch for both sensors!
