User Guide for SRAQ-G013
Product Description
The SRAQ-G013 gas sensor module detects the presence and concentration of Hydrogen(H
corresponding to the gas concentration. Having high sensitivity to this flammable gas, the sensor module can detect hydrogen gas concentrations
ranging from 50 to 10,000 ppm. The SRAQ-G013 has both analog and level outputs with adjustable output sensitivity.

  • Page 1 HYDROGEN (H ) SENSOR MODULE User Guide for SRAQ-G013 Product Description The SRAQ-G013 gas sensor module detects the presence and concentration of Hydrogen(H ) gas. Integrated circuitry produces a voltage signal corresponding to the gas concentration. Having high sensitivity to this flammable gas, the sensor module can detect hydrogen gas concentrations ranging from 50 to 10,000 ppm.
  • Page 2 Technical Parameters Working Voltage 5 VDC ± 0.2 V Working Current <150 mA Gas Detection Hydrogen 50  10000 ppm (Hydrogen) Detection Concentration Preheating Time >30 mins Response Time ≤1 sec Recovery Time ≤30 sec 0  5 V (Non-linear) Aout (Analog signal) Output Mode Dout (Level signal)
  • 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.
