Waterproof Ultrasonic Sensor with Probe

Waterproof Ultrasonic Sensor with Probe

The Waterproof Ultrasonic Sensor with Probe is a durable distance measurement module designed for use in harsh and outdoor environments. With a sealed ultrasonic probe and separate control board, it provides accurate, non-contact distance and level measurement even in wet or dusty conditions.

Key Features

• Waterproof Ultrasonic Probe – Suitable for outdoor and liquid environments
• Accurate Distance Measurement – Reliable non-contact sensing
• Long Measurement Range – Typically up to 4m–6m (model dependent)
• Separate Control Board – Keeps electronics safe from moisture
• Multiple Output Options – UART / TTL / Analog / PWM (varies by model)
• Stable Performance – Works in humid and dusty conditions

Applications

• Water Level Monitoring – Tanks, reservoirs, and wells
• Industrial Automation – Distance sensing in harsh environments
• Outdoor Projects – Smart irrigation and flood monitoring
• Robotics – Obstacle detection in rugged conditions
• IoT Systems – Remote level and distance tracking

Technical Specifications

• Sensor Type: Ultrasonic (waterproof probe)
• Operating Voltage: Typically 5V – 12V (model dependent)
• Measuring Range: ~20 cm to 400–600 cm
• Accuracy: ±1 cm (typical)
• Output Type: UART / TTL / Analog / PWM (depends on module)
• Frequency: ~40 kHz
• Operating Temperature: -10°C to +70°C (varies by model)

A rugged ultrasonic distance sensor ideal for water level and outdoor sensing applications.

Why Choose Waterproof Ultrasonic Sensor?

• Reliable in wet and harsh environments
• Non-contact measurement (no wear and tear)
• Easy integration with Arduino, ESP32, etc.
• Ideal for water level and outdoor projects
• More durable than standard ultrasonic sensors

⚠️ Important Notes

• Only the probe is waterproof — keep control board dry
• Minimum distance (~20 cm) must be maintained
• Avoid angled surfaces for accurate readings
• Requires stable power supply
• Cable length may affect signal quality
