Gas sensors also known as gas detectors are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration. It includes all MQ series gas sensors this module Module can be used to sense Carbon Monoxide and Methane Gas, Hydrogen Gas, etc. This type of device is used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacturing processes and emerging technologies such as photovoltaic and in firefighting.
