Air Quality (VOC) Sensor
Performance
Scope of application: MQ-K2 gas sensors apply to the home device monitoring harmful gas, such as automatic exhaust device, air cleaner, kitchen ventilator and so on. It’s sensitive to ammonia(NH4), hydrogen(H2), alcohol(C2H6O), methane(CH4), propane(C3H8), glycerol, styrene(C8H8), propanediol(C3H8O2), hydroxybenzene, methylbenzene(C7H8), ethylbenzene(C8H10), dimethylbenzene(C8H10), formaldehyde(CH2O) and any other organic volatile gas, smog and soot.
