This Waterproof Ultrasonic Obstacle Sensor is similar to the ones used in automotive applications.
It consists of a separate waterproof transducer and control board, allowing you to position the sensing element away from the circuitry — ideal for harsh environments.
Industrial-grade waterproof ultrasonic distance sensor.
Separate waterproof sensing probe and control circuit.
Measures distance from 250mm to 4500mm.
High accuracy and strong anti-jamming capability.
Works like an HC-SR04 but designed for rugged and wet conditions.
Compatible with Arduino and other microcontrollers.
Operating Voltage: 5V DC
Measuring Range: 250mm – 4500mm
Operating Current: Low power consumption
Working Principle:
Send an ultrasonic burst at 40KHz.
Measure time taken for echo to return.
Distance = (Time × 340 m/s) ÷ 2.
Control Interface:
TRIG pin: 5V pulse of 10μs or more
ECHO pin: High-level signal output when reflection is detected
Connections:
5V — Power Supply
GND — Ground
RX / TX — Communication Ports (optional)
Included in Package:
1 x Waterproof Ultrasonic Obstacle Sensor with 2.5m separate probe
Horizontal distance measurement
Obstacle avoidance in robots and vehicles
Traffic monitoring and control systems
Security systems and industrial automation
AI research and smart projects requiring distance sensing in harsh environments
