This MQ6 Gas sensor can detect or measure gases like LPG and butane. The MQ6 gas sensor is a metal oxide semiconductor (MOS) sensor that is used to detect the presence of LPG (liquefied petroleum gas) and butane gases.

MQ Gas Sensor can also use to detect the presence of alcohol, cooking fumes, and cigarette smoke. The sensor is made up of a sensing element, which is a ceramic disc coated with tin dioxide, and a heater coil.

When the sensor is exposed to a gas, the resistance of the sensing element changes. This change in resistance can measure to determine the concentration of the gas.

The MQ6 Gas Sensor is a relatively simple device to use. It is powered by a 5V supply, and the output is an analog voltage. The output voltage will increase as the concentration of the gas increases. The sensor can use with a microcontroller to measure the output voltage and determine the concentration of the gas.

MQ6 gas sensor is a relatively sensitive sensor, and it can detect gas concentrations in the range of 200 to 10000 parts per million (ppm). This means that the sensor can detect a gas when it is present in the air at a concentration of 200 parts per million, or 1 part per 50000 parts of air. The sensor can also detect gas concentrations up to 10000 ppm, which is equivalent to 1 part per 1000 parts of air.

The MQ6 gas sensor is not as sensitive to low concentrations of gas as some other sensors, but it is still a good choice for applications where a moderate level of sensitivity requires.
