MQ7 is a higly sensitive analogue output sensor which is commonly used as carbon monoxide(CO) gas sensor in MQ sensor series. It is a very popular Gas Sensor in verious sectors. The output voltage of the gas sensor increases if the concentration of gas increases. The sensitivity of the sensor is adjustable by the Potentiometer. The MQ7 who is arduino compatible.

The working voltage of MQ7 gas sensor is 5 volt DC and it draws around 350mW. This sensor is capable of detecting carbon monoxide(CO) gas concentrations anywhere from 20ppm – 2000ppm.

Applications:

  • They are used in gas detecting equipment for carbon monoxide(CO) in family and industry or car
  • Suitable for detecting of carbon monoxide(CO)
