Waterproof Ultrasonic Sensor, Reversing Radar Sensor with Separate Probe

This Waterproof Ultrasonic Sensor is also known as JSN-SR04T is an easy to use waterproof ultrasonic distance sensor with a range of 25 to 450 cm. If you are planning to build a water level measuring system or if you need to take other distance measurements outside, then this is the sensor you need! The sensor comes with a 2.5 m long cable that connects to a breakout board which controls the sensor and does all the processing of the signal. Note that only the sensor and the cable itself are waterproof, if you get water onto the breakout board, the sensor might stop working. An ultrasonic distance sensor works by sending out ultrasound waves. These ultrasound waves get reflected back by an object and the ultrasonic sensor detects them. By timing how much time passed between sending and receiving the sound waves, you can calculate the distance between the sensor and an object. DATA SHEET can be downloaded from below link.
