سنسور گاز هیدروژن MQ-8

MQ-8 gas sensor is suitable for sensing is Hydrogen Gas which with lower conductivity in clean air.
When hydrogen gas exists, the sensor’s conductivity gets higher along with the gas concentration rising.
MQ-8 gas sensor has high sensitivity to hydrogen gas, also has anti interference to other gases.
The sensor’s output is an analog resistance.
This sensor can detect hydrogen, especially city gas.
It is a kind of low-cost sensor for kinds of applications.
Features
It has good sensitivity to hydrogen gas in wide range.
Long lifespan, low cost and simple drive circuit
Small sensitivity to alcohol, LPG,cooking fumes
Stable and long life
Selective digital/analog output using toggle switch
High sensitivity and response time
