Product Specification

Hydrogen Sensor H2 Gas Sensor

 

Specification:

Sensitive material MQ-K8 gas sensor is used in clean air low conductivity tin oxide (SnO2).When the sensor is exposed in the presence of hydrogen, conductivity sensor with increasing concentration of combustible gases in air increases .Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal.MQ-K8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory. This sensor can detect a wide range of hydrogen gas, city gas in particular, is a low-cost sensor for a variety of applications.

 

Character:

1. In a wide range of concentrations with good sensitivity to hydrogen

2. Long life , low cost

3. Simple drive circuit

 

Application:

1. Household gas leak alarm

2. Industrial combustible gas alarm

3. Portable gas detector
