Water Proof Ultrasonic Sensor

An ultrasonic rangefinder in a sealed housing, designed for applications where a bare HC-SR04 is unsuitable, including outdoor installations, water tank level measurement, and dusty or humid environments. It uses ultrasonic echo timing to measure distance, while the sealed transducer withstands rain, splashes, and condensation. A practical choice for measuring liquid levels from above the surface. Measurement range: approximately 25 cm to 4.5 m; Interface: Trigger/Echo digital pulse ; Sealed waterproof transducer for rain, splashes, and condensation; Ideal for water tank level measurement from above; Works in complete darkness and is unaffected by object colour ; Simple interface for Arduino and other microcontrollers.
