Learn how to interface the A0221AU / A02YYUW Waterproof Ultrasonic Sensor with an ESP32 microcontroller. In this video, I demonstrate how to connect the sensor, upload the code, and perform a real-world underwater test to measure distance accurately.

Unlike standard ultrasonic sensors (like HC-SR04), this waterproof module interacts via Serial Communication and is perfect for outdoor or water-level monitoring projects.
