MQ6 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 istance, 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 :
- Gas leak detection system
- Fire/Safety detection system
- Domestic gas leakage detector
- Industrial Combustible gas detector
- Portable gas detector
- Gas leak alarm
- Gas detector
