Carbon Monoxide MQ-7 Gas Sensor | Mbed

· The MQ-7 sensor detects carbon monoxide gas concentrations in the air and alerts the user when the levels go past a safe threshold. Carbon Monoxide is a poisonous gas that has no color, odor, or taste. It is produced as a result of incomplete combustion ( when there is not enough oxygen in the air to make carbon dioxide). Household sources of carbon monoxide include: gas stoves car …

Carbon Monoxide Gas Sensor MQ-7 -

· 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 MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
