Arduino and mics-5524 gas sensor example

In this example we look at a MICS 5524 gas module

The MiCS-5524 is a robust MEMS sensor for indoor carbon monoxide and natural gas leakage detection; suitable also for indoor air quality monitoring; breath checker and early fire detection.

Detectable gases

• Carbon monoxide CO 1 – 1000ppm
• Ethanol C2H5OH 10 – 500ppm
• Hydrogen H2 1 – 1000ppm
• Ammonia NH3 1 – 500ppm
• Methane CH4 >1000ppm

One thing to note is that this sensor is sensitive to multiple gasses, as you can see above – but does not know which gas it is

Code

void setup()
{
  Serial.begin(9600);
  Serial.println("MiCS-5524 demo!");
}
 
void loop()
{
  int reading = analogRead(A0);
  Serial.println(reading);
  delay(100);
}

Output

OPen the serial monitor, if you have a gas source such as alcohol then you could test this further
