Water Proof Ultrasonic Sensor

The Waterproof Ultrasonic Sensor is a distance measuring module designed for reliable object detection in wet, dusty, or outdoor environments. It is commonly based on the JSN-SR04T architecture and work using ultrasonic sound waves to calculate distance by measuring the time taken for an echo to return after transmission.

Unlike standard ultrasonic sensors (like HC-SR04), this module features a separate waterproof probe, making it ideal for applications where the sensor must be exposed to water, humidity, or harsh environmental conditions.
