Large Ultrasonic (Sonar) Sensor with Horn and UART Output

The A19NYMW ultrasonic distance sensor is a compact and waterproof device that is used to measure distances and detect objects. It operates using ultrasonic waves, emitting a high-frequency sound pulse and measuring the time it takes for the wave to bounce back after hitting an object. The resulting time-of-flight measurement is used to calculate the distance to the object. A19NYMW supports multiple output methods, including UART, PWM, switch, and RS485, and can be powered by a DC voltage of 3.3-5V.
