Waterproof Ultrasonic Distance Sensor | 5V Module | Compoden
Waterproof Ultrasonic Distance Transducer Sensor – 20-600cm Range
This waterproof ultrasonic distance sensor uses sound waves to measure distances from 20 cm to 600 cm with ±1 cm accuracy. Its sealed housing makes it safe for wet or dusty environments—ideal for outdoor projects, tank level monitoring, or obstacle detection in rain. The module outputs a TTL signal for easy interfacing with microcontrollers.

Compatibility
This sensor works with 5V microcontrollers like Arduino Uno, Mega, and standard ESP32 boards. For 3.3V devices such as Raspberry Pi or ESP8266, a level shifter on the Echo pin is recommended. It pairs easily with I2C LCD modules or SD card shields for displaying or logging measurements.
Wiring Notes
Connect VCC to 5V, GND to ground, Trig to a digital output pin, and Echo to a digital input pin. The Echo pin outputs a 5V pulse; if using a 3.3V controller, insert a voltage divider or level shifter. Avoid pulling excessive current from the Echo pin.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it works directly with 5V Arduino boards. Just connect Trig and Echo to digital pins and use a standard pulseIn function in your code.
Can I submerge the sensor completely?
The sensor head is IP67 rated, meaning it withstands temporary immersion up to 1 meter, but it is primarily designed for air-based measurement in wet conditions. Avoid permanent underwater operation.
How does it compare to HC-SR04?
This sensor offers a longer range (600 cm vs 400 cm) and a waterproof transducer, making it more durable for outdoor and humid applications.
