Sample code

Arduino
This is the sample code to interface the PIR motion sensor with the NodeMCU ESP8266 development board.
int Sensor = A0;

void setup(){
  Serial.begin(9600);
}

void loop(){
  sensorValue = analogRead(sensor);
  Serial.print("Sensor value= ");
  Serial.print(sensorValue);
  delay(500);
}
