Combustible Gas Sensor - MQ-K5

Product Specification

Combustible Gas Sensor MQ-K5

Specification:

MQ-K5 gas sensors used in gas sensingmaterial is tin oxide (SnO2), low conductivity in clean air. When a combustiblegas sensor in which the environment, the sensor's conductivity increases withthe
air of combustible gas concentrations increase with increasing. Using a simplecircuit to the conductivity change is converted to output signals correspondingto the concentration of the gas.MQ-K5 gas sensor for butane, propane, methanesensitivity, a better balance between methane and propane. This sensor candetect a variety of flammable gas, especially natural gas, is a suitable low-cost sensors to a variety of applications.

Character:

1. Good sensitivity in a wide concentrationrange of combustible gases

2. High sensitive with Butane, propane,methane

3. Long-life, low-cost

4. Simple drive circuit
