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.
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.
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.
MQ-6 gas sensor has high sensitivity to Propane, Butane, and LPG, also the response to Natural gas. The sensor could be used to detect different combustible gas, especially Methane, it is with low cost and suitable for different application.
Continuous Analog output
Low cost and compact size
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)
Can be resistant to ethanol steam, LPG (petroleum), smoke interference
