## Description

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. Specifications Operating Voltage – 3.3–5 V Average Current – <15 mA Blind Zone – 28 cm Detection Range (Flat Object) – 28–750 cm Output – UART (9600 bps) Response Time – 100 ms Probe Centre Frequency – 40 kHz ± 1.0 kHz Sensing Angle – 55° with bell-mouth, 40° without Waterproof Grade – IP67 Operating Temperature – -15 to 60°C Storage Temperature – -25 to 80°C Ideal For Reversing / parking distance sensors Obstacle-avoidance robots Object proximity detection Outdoor or wet-environment distance measurement Resources Product Wiki Package Contents 1× A01NYUB Waterproof Ultrasonic Sensor 1× Removable Bell-Mouth
