MQ-6 LPG Butane Sensor Module

The MQ6 ( 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 operates 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.

Specifications:

• 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
