Eight-Beam Underwater Obstacle Avoidance Sensor

Measurement Principle

The sensor operates on ultrasonic measurement principles. Ultrasonic signals emitted by the probe reflect off liquid or solid media and return to the same probe. Distance measurement is calculated by analyzing the time difference between signal emission and reception.

L = (v * t) / 2
L: Distance from probe to material surface (meters)
v: Temperature-compensated sound velocity (m/s)
t: Sound wave travel time (seconds)

Product Description

This multi-beam ultrasonic ranging device extends standard ultrasonic ranging through software-implemented round-robin testing. The system features multiple transmissions with single reception capability, enabling omnidirectional distance measurement for underwater obstacle avoidance applications. Data storage and Modbus protocol communication support both passive and active data upload modes.

Product Features

Multi-channel round-robin testing capability
High-speed response with precision measurement
IP68-rated transducer protection
TTL communication with read/write functionality
4-pin aviation plug for simplified installation
Wide voltage input range: 10.8VDC-26.4VDC

Product Applications

Underwater position and distance detection
Obstacle avoidance for underwater robotics
Distance-setting applications in aquatic environments
