Surilli Basic M0 with MQ7 Gas Sensor

Code

SurilliBasicM0_MQ7

C/C++
const int AOUTpin = 0; // The AOUT pin of the CO sensor goes into analog pin A0 of Surilli Basic M0
const int DOUTpin = 12; // The DOUT pin of the CO sensor goes into digital pin 12 of Surilli Basic M0
int limit;
int value;

void setup() 

{
  
    SerialUSB.begin(115200); // Sets the baud rate
    pinMode(DOUTpin, INPUT); // Sets the pin as an input to the Surilli Basic M0
    SerialUSB.println("Date & Time, Air Quality PPM");
  
}

void loop()

{
   
   value= analogRead(AOUTpin); // Reads the analaog value from the CO sensor's AOUT pin
   limit= digitalRead(DOUTpin); // Reads the digital value from the CO sensor's DOUT pin
   SerialUSB.print("CO value: ");
   SerialUSB.println(value); // Prints the CO value
   SerialUSB.print("Limit: ");
   SerialUSB.println(limit); // Prints the limit reached as either LOW or HIGH (above or underneath)
   delay(1000);
