Sensitive material of MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, the sensor’s conductivity is more higher along with the gas concentration rising. MQ-6 gas sensor has high sensitity to Propane, Butane and LPG, also response to Natural gas.

Technical Specification:

• Sensor type: semiconductor
• Operating Voltage: +5V
• Analog output voltage: 0V to 5V
• Digital Output Voltage: 0V or 5V (TTL Logic)

Features:                                  

• High sensitivity to LPG, iso-butane, propane
• Small sensitivity to alcohol, smoke
• Fast response
• Stable and long life
• Simple drive circuit

Applications:          

• Detect or measure Gases like LPG, and butane
• Air quality monitor
• Gas leak alarm
