Product details
Semiconductor hydrogen rsMQ-8 gas-sensitive material used in the clean air low conductivity tin oxide(SnO2). When the r is exposed in the presence of hydrogen gas, the conductivity r with increasing concentration of combustible gases in air increases. Use simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal.MQ-8Gas rHydrogenHigh sensitivity,Monitoring other hydrogen-containing gas is also very good. Such rsIt can detect a variety of hydrogen-containing gases, in particularCity Gas,Is a low-cost rs for a variety of applications.
and Applications:
·For over a wide concentration rangeHydrogenGood sensitivity
* Long life, low cost
· Simple drive circuit can be
·Household gas leak alarm
·Industrial combustible gas alarm
·Portable gas detector
