Example Code for Arduino-Gas Value Reading

Hardware Preparation

• DFRduino UNO R3 with IO Expansion Shield and USB Cable A-B x1
• Gravity: Analog Propane Gas Sensor (MQ6) x1
• Gravity Analog Cable (Gift) x1

Software Preparation

• Arduino IDE
• Download and install the XXX Library. (About how to install the library?)

Sample Code

///Arduino Sample Code
void setup()
{
  Serial.begin(9600); //Set serial baud rate to 9600 bps
}
void loop()
{
int val;
val=analogRead(0);//Read Gas value from analog 0
Serial.println(val,DEC);//Print the value to serial port
delay(100);
}
