Description
Waterproof Ultrasonic Distance Sensor – IP67 Rated, High‑Precision Range
This rugged ultrasonic transducer delivers reliable distance measurement up to 6 m with an accuracy of ±2 mm, even in submerged environments. Built with a conformal coating and stainless‑steel housing, the sensor meets IP67 standards, allowing water immersion up to 1 m for 30 minutes without performance loss. Its low‑power 3.3 V/5 V operation (≤50 mA) and TTL/ UART outputs make it ideal for battery‑powered robots, marine navigation, and industrial level monitoring.
With an adjustable trigger pulse (10 µs) and a narrow 120° beam angle, the device minimizes cross‑talk and environmental noise. The internal micro‑controller filters echoes and compensates for temperature drift, ensuring stable readings across -20 °C to +60 °C. Package size is compact (36 mm × 25 mm × 35 mm), facilitating integration into tight spaces.
- Operating Voltage: 3.3 V–5.5 V (standby 15 mA, active < 50 mA)
- Measurement Range: 0.2 m – 6 m (typ. 0.5 m spacing between samples)
- Accuracy: ±2 mm < 2 m, < 1 % beyond; ±5 mm up to 6 m
- Common Use Case: Submerged level detection in tanks, autonomous underwater vehicle (AUV) range finding, and waterproof proximity sensing in consumer drones.
