Waterproof Ultrasonic Obstacle Sensor, Reversing Radar Sensor with Separate Probe

The module is capable of providing information of the objects between the distance range of 250 mm to 4500 mm. The great advantage of using this Waterproof Ultrasonic Obstacle Sensor is you can put the sensing element far away from all the control circuitry.
This Ultrasonic Distance Sensor is an industrial-grade sensor to measure distance. Interfacing with it is the same as another cheap ultrasonic sensor, but it offers better performance and is compatible with harsher environments and is waterproof too! It can be easily interfaced with Arduino and Sample codes and projects are available.

The basic working principle:
Turn on TRIG Pin to 5V for at least 10uS
The module will then automatically send 8 40KHz tones and automatically detect when the signal return after reflecting back from the object
Upon detecting the signal, a high-level signal is outputted through the IO Pin ECHO. By keeping track of the time duration between transmitting and receiving the signal, the distance can be calculated. Distance = (Time to Receive Reflected Signal * speed of sound (340M/S)) /2
