RCWL-1670 Waterproof Ultrasonic Distance Sensor 400cm

RCWL-1670 is a waterproof transceiver ultrasonic measurement module. It can measure in the range of 2cm-400cm. This product, which can operate between 3-5V, has an ultra-low power consumption. External control software is compatible with the HC-SR04 module. It is also suitable for use in outdoor environments because it is resistant to water and dust.

Arduino Sample Code:

const int pingPin = 13;

int inPin = 12

void setup() {

Serial.begin(9600);

}

void loop()

{

long duration, cm;

pinMode(pingPin, OUTPUT);

digitalWrite(pingPin, LOW);

delayMicroseconds(2);

digitalWrite(pingPin, HIGH);

delayMicroseconds(5);

digitalWrite(pingPin, LOW);

pinMode(inPin, INPUT);

duration = pulseIn(inPin, HIGH);

cm = microsecondsToCentimeters(duration);

Serial.print(cm);

Serial.print("cm");

Serial.println();

delay(100);

}

long microsecondsToCentimeters(long microseconds)

{

return microseconds / 29 / 2;

}
