SMOKE AND FLAMMABLE GAS SENSOR MODULE
User Guide for SRAQ-G004
Product Description
The SRAQ-G004 gas sensor module detects the presence and concentration of smoke and other flammable gases such as butane, propane,
methane and hydrogen. Integrated circuitry produces a non-linear voltage signal corresponding to the smoke and gas concentrations. With high
sensitivity, the SRAQ-G004 sensor module can detect smoke in the range of 100-1000 ppm and flammable gases in the range of 300 to 10,000 ppm.
Features

  • 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.
