How to Use the MQ7 Carbon Monoxide Sensor ...

The MQ7 carbon monoxide sensor is especially designed to be sensitive to carbon monoxide (CO) gas which is emitted by vehicles, factories, etc. Since this gas is considered toxic to humans at certain levels, concentration of CO is used to determine the air pollution in a given area.


MQ9 Semiconductor Sensor for CO/Combustible Gas

MQ9 Semiconductor Sensor for CO/Combustible Gas Sensitive material of MQ9 gas sensor is SnO 2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by ). The sensor’s conductivity is more higher along with the gas concentration rising. When high


MQ7 CO Module Setup Sensors Arduino Forum

· You wire that module right to your Arduino, all needed components are on the module. Here is a tutorial for that family of sensors,use the AOUT pin on the MQ7 module. The trim cap is for adjusting DOUT. Accurate calibration is difficult at home, the datasheet tells you to allow the module to preheat "No Less Than 48 Hours".
