Waterproof Ultrasonic Distance Sensor V2.0 (24-500cm, 3.3-5V)

The Waterproof Ultrasonic Distance Sensor V2.0 provides precise non-contact distance measurements from 24 cm to 500 cm. Designed for reliable outdoor use, it operates across 3.3V to 5V systems and is well suited for makers, students, and robotics hobbyists developing outdoor sensing projects.

Extended measurement range

The sensor detects obstacles and measures distances reliably between 24 cm and 500 cm. This wide sensing boundary accommodates a broad variety of outdoor monitoring and robotics applications.

Fine measurement resolution

With a 3 mm resolution, the unit captures minute distance shifts accurately. This ensures steady, fine-grained feedback for precision positioning tasks.

Built-in temperature compensation

Integrated temperature compensation maintains reading accuracy despite changing ambient conditions. This design delivers stable outdoor measurements across shifting daily temperatures.

Flexible supply voltage

Operating across 3.3V to 5V power inputs, this sensor integrates seamlessly with standard microcontrollers and development boards. It eliminates the need for external level shifting in most low-voltage systems.
