DESCRIPTION
The Ultrasonic Transducer Waterproof uses sonar to determine distance to objects like bats or dolphins do. This module offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). Ranging accuracy can reach up to 5mm. This ultrasonic module is integrated with wire enclosed waterproof probe, suitable for wet and harsh measurement conditions.
Sensor Working Principle:
- IO trigger through supplying at least 10us sequence of high level signal
- The module automatically send eight 40kHz square wave and detect any response from the returning pulse signal
- If there is signal returning, ECHO pin will pulse high. By calculating the difference in timing from sending to receiving and dividing by the speed of sound we will be able to get the distance of the object
- Distance = duration / 2 / 29.1
