COMBUSTIBLE GAS SENSOR MODULE
User Guide for SRAQ-G009
Product Description
The SRAQ-G009 gas sensor module detects the presence and concentration of flammable gases such as butane, propane, methane as well as other
gases containing carbon monoxide. Integrated circuitry produces a non-linear voltage signal corresponding to the smoke and gas concentrations. With
high sensitivity, it can detect smoke in the range of 100-1000ppm and flammable gases in the range of 300  10,000 ppm.

  • Page 3 Notes Confirm the polarity and the voltage of the power supply before powering ON the sensor. The analog output of this module is non-linear. When connect to microcontroller, it should be connected to ADC interface of the microcontroller. The relationship between the resistance ratio and the concentration is a logarithmic relationship.
