sending vibration sensor data

[sunnyaoc]

Please I need some help!
I want to send vibration sensor (801S) pulse data from one lgt-rf nano to another but couldn't.
here is the vibration sensor code
#define valPin D4 //sensor
void setup(){

pinMode(valPin, INPUT);
Serial.begin(9600);

Serial.println("impact detection on pipeline");
}
void loop(){
long vibMeasure = vib()/1000;
delay(100);
Serial.println(vibMeasure);

long vib(){
long vibMeasure = pulseIn (valPin, HIGH); //wait for the pin to get HIGH and returns measurement
return vibMeasure;
delay(100);
}

I want to send vibMeasure!
