MQ-6 Propane Butane LPG LNG Gas Sensor Module utilizes an MQ-6 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ-6 gas sensor is highly sensitive to LPG, iso-butane, propane and less sensitive to alcohol, cooking fume and cigarette smoke. It could be used in gas leakage detecting equipment’s in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes.

Sensitive material of MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to the corresponding output signal of gas concentration.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

Features:

• Good sensitivity to Combustible gas in a wide range
• High sensitivity to Propane, Butane, and LPG
• Long life and low cost
• Simple drive circuit
• An indication of the signal output
• Dual signal output (analog output, and TTL level output)
• The TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
• 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
• High sensitivity to hydrogen.
• Can be resistant to ethanol steam, LPG (petroleum), smoke interference.
• Has a long life and reliable stability.
• Fast response and recovery characteristics.

Applications of MQ6 LPG Gas Sensor Module:

• Gas leak detection system
• Fire/Safety detection system
• Domestic gas leakage detector
• Industrial Combustible gas detector
• Portable gas detector
• Gas leak alarm
• Gas detector
