Carbon Monoxide Gas Sensor MQ7 Arduino Project Hub

20200402· Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem. I followed the recommendation to use a 10KOhm resistor and soldered the MQ7 to the PCB. It doesn''t matter which side and how around (you have 4 options), because no …

How to Use the MQ7 Carbon Monoxide Sensor ...

Before we can use this formula in a sketch, we need to determine R0 of the MQ7 sensor first. This varies between devices so there is a need for actual testing. From the loglog plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then only RS varies for every gas. RS is the sensor resistance and forms a voltage ...
