This is a simple-to-use MQ-6 Liquefied Petroleum Isobutane Propane Gas Sensor module, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm. The MQ-6 Liquefied Petroleum Isobutane Propane Gas Sensor module particulate sensor uses a Potentiometer to change the detection range of the sensor!
The sensitive material of the MQ-6 gas sensor is a tin oxide (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 a simple electro circuit, Convert the change of conductivity to the corresponding output signal of gas concentration.
Application
The domestic gas leakage detector
Industrial Combustible gas detector
Portable gas detector
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.
