MQ-6
The MQ6 Gas Sensor is a type of gas detection device that is designed to detect specific gases in the air, particularly Liquefied Petroleum Gas (LPG), Isobutane, and Propane. These gases are commonly used in household appliances like stoves, heaters, and gas-powered vehicles. The MQ-6 sensor module is part of the MQ series of gas sensors produced by the company Winsen, and it operates based on the principle of chemical resistance change.

General Description:
The MQ6 Gas Sensor is a type of gas detection device that is designed to detect specific gases in the air, particularly Liquefied Petroleum Gas (LPG), Isobutane, and Propane. These gases are commonly used in household appliances like stoves, heaters, and gas-powered vehicles. The MQ-6 sensor module is part of the MQ series of gas sensors produced by the company Winsen, and it operates based on the principle of chemical resistance change.
Working Principle:
The MQ-6 gas sensor operates on gas conductivity principles, reacting to specific gases with its sensitive layer. When the target gas contacts the sensor, its electrical resistance changes, generating an electrical signal. This signal’s voltage varies with gas concentration, typically decreasing as the concentration rises. An analog-to-digital converter (ADC) reads this voltage for microcontroller processing. Environmental factors like temperature and humidity influence sensor output, requiring calibration for accuracy. Preheating the sensor ensures reliable readings.
Specifications:
1. It operates on a voltage of 5V DC.
2. Detecting Range: It can detect gas concentrations within the range of 200 to 10,000 parts per million (ppm).
3. Relative Humidity: 95% RH.
4. It operates within a temperature range of -20 to 40 degrees Celsius.
5. Having an IC chip LM393 voltage comparator.
6. Good sensitivity to Combustible gas in a wide range.
7. High sensitivity to Propane, Butane, and LPG.
8. An indication of the signal output.
9. Dual signal output (analog output, and TTL level output).
10. High sensitivity to hydrogen.
11. Can be resistant to ethanol steam, LPG (petroleum), and smoke interference.
