Carbon Monoxide MQ7 Gas Sensor | Mbed

· The MQ7 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 …
