Waterproof Ultrasonic Sensor – JSN-SR04T

With this water-resistant ultrasonic sensor you can easily measure a distance in a moist environment. It works just like an HC-SR04. The sensor with wire is water resistant.

Note: The JSN-SR04T is less stable compared to the HC-SR04. The sensor has more problems measuring small/moving objects and can therefore give deviating values. This module has only one sensor that works as a sender and receiver and has a bigger angle in which it operates. On the other hand, the sensor (not the PCB!) is moisture-resistant and splash-proof.

Specifications:
