Couldn't load pickup availability
The A02YYUW Waterproof Ultrasonic Distance Sensor is a reliable solution for distance measurement in challenging environments where water and dust protection is essential. With its IP67 waterproof rating, this sensor can be safely used outdoors, in industrial settings, or any application exposed to moisture and dust.
The sensor offers an impressive detection range from 3cm to 450cm with a resolution of 1mm, making it suitable for various distance measurement projects from short-range obstacle detection to long-range monitoring.
The integrated UART communication interface allows for simple connection to Arduino, Raspberry Pi, or other microcontroller platforms without complex wiring or additional components.
This ultrasonic sensor features a compact design with a pre-attached 1-meter waterproof cable, allowing for easy installation in tight spaces or remote locations. The sensor operates on a wide voltage range from 3.3V to 5.5V DC and consumes only 10mA during operation, making it ideal for battery-powered projects.
With a blind zone of just 3cm, the A02YYUW can detect objects at very close range, which is particularly useful in robotics and automation applications.
The sensor's temperature compensation feature ensures consistent performance across varying environmental conditions, while its narrow 15° beam angle provides focused detection for accurate measurements.
Whether you're building a water level monitor, parking assistant, or industrial automation system, this waterproof ultrasonic sensor delivers reliable performance in demanding conditions.
