A waterproof ultrasonic distance sensor with UART serial output. The A01NYUB measures distance by timing the ultrasonic pulse echo and outputs the result directly via asynchronous serial at 9600 bps — no external signal processing needed. With the included removable bell-mouth fitted, the effective range extends to 7.5 m.

The closed probe design is waterproof (IP67) and dustproof, with penetration through smog and dust. Connects easily to Arduino, Raspberry Pi, or any MCU with a serial interface.
