Description
Features of MQ6 Gas sensor
- Operating Voltage is +5V
- Can be used to detect LPG or Butane gas
- Analog output voltage: 0V to 5V
- Digital Output Voltage: 0V or 5V (TTL Logic)
- Preheat duration 20 seconds
- Can be used as a Digital or analog sensor
- The Sensitivity of Digital pin can be varied using the potentiometer
Where to use MQ-6 Gas sensor?
The MQ-6 Gas sensor can detect or measure gases like LPG and butane. The MQ-6 sensor module comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers.
So, if you are looking for a sensor to detect or measure gasses like LPG, or methane with or without a microcontroller, then this sensor might be the right choice for you.
Pin Configuration
| Pin No: | Pin Name: | Description |
| 1 | Vcc | This pin powers the module, typically the operating voltage is +5V. |
| 2 | Ground | Used to connect the module to system ground. |
| 3 | Digital Out | You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer. |
| 4 | Analog Out | This pin outputs 0-5V analog voltage based on the intensity of the gas. |
