A02YYUW Waterproof Ultrasonic Sensor
We have ✅ 5 available of the DF-SEN0311 in our Sydney warehouse. An extra 1307 units available with a short lead time.
A commercial-grade waterproof ultrasonic distance sensor with UART serial output. The A02YYUW features a much smaller blind zone (3 cm) and wider sensing angle than many comparable sensors, plus penetration through smog and dust for reliable outdoor use.
The closed separated-probe design is waterproof (IP67) and dustproof, making it well suited to harsh and moist environments. All signal processing is integrated inside the module — connect via UART at 9600 bps and read distance values directly.
