JSN-SR04T Waterproof Ultrasonic Distance Sensor

This ultrasonic distance sensor has a waterproof probe on a 2.5 m cable, while the evaluation board stays dry. It is suitable for measurements outdoors and in humid environments, for example for the water level in a tank. It is controlled via Trig and Echo like an HC-SR04, so libraries and examples for it can be reused.
