CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

20140329· CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable …

Carbon Monoxide Gas Sensor MQ7 Arduino Project Hub

20200402· I had previously published a project with an MQ sensor and received a lot of critical feedback on it. 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.

Create Your Own CO Detector DigiKey

CO sensor prototype with an Arduino board. (Image courtesy of SPEC Sensors) So as a final example, with this setup we are measuring Volts. First subtract the zero voltage of V, giving V or 55 mV. Now divide by our new sensitivity of mV/ppm and we are measuring 240 ppm CO, which is a dangerous level to breath for long periods of time. Summary and next steps: By using the ...
