SMOKE AND FLAMMABLE GAS SENSOR MODULE
User Guide for SRAQ-G107
Product Description
The SRAQ-G107 smoke and flammable gas sensor detects the presence and concentration of smoke and other flammable gases such as liquefied
petroleum gas, propane, butane and hydrogen. Integrated circuitry produces a non-linear voltage signal corresponding to the smoke and gas
concentrations. With high sensitivity, the SRAQ-G107 is well suited for use in detecting flammable gas leaks and triggering alarms.
Features
Highly sensitive to propane, butane and hydrogen
Wide detection range 0  1000 ppm
Analog outputs
35 mm DIN rail mount
Applications
Smoke alarms
Industrial settings
Chemical manufacturing
Portable gas detectors
Anywhere combustible gas concentration is a concern

  • Page 3 Mounting Diagram Mount the PCBA to the enclosure with screws. Hole diameter 3mm, pitch distances as per the diagrams given below. Typical Sensitivity Curve The calculation of the resistance ratio according to the output voltage is as follows: The sensor is energized in relatively clean air for more than half an hour and after measure the output voltage value of Aout. VCC is the power supply voltage, 5 VDC RL is the load resistance VRL = Aout = Vair value...
