The higher the concentration of the gas, the higher the conductivity. Use a simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal.
Applications
Gas leak detection for mobile phones, computers, and other consumer electronics applications; also apply for a home, commercial use of the combustible gas leakage monitoring devices, gas leak detectors, fire/security detection system.
