DC 5V Waterproof Ultrasonic Module Distance Measuring Transducer Sensor

This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 200cm sensing range.

We have used the HC-SR04 Ultrasonic Distance Sensor many times  and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you'll need.

However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.

For these circumstances you can use this sensor, in more weathered states, even outdoors.

Sensor Usage

Basic working principle

(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
