MQ-6 Gas Sensor Module – Detects LPG, Propane, and Isobutane

Description

• Operating Voltage: 5V DC
• Indication of the signal output 
• Dual signal output (analog output, and TTL level output) 
• 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

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.
