Anti-interference Methane Sensor CH4 Sensor - MQ-K10

Product Specification

Anti-interference Methane Sensor CH4 Sensor MQ-K10

?

Specification:

MQ-K10 gas sensors used in gas sensing material is tin oxide (SnO2), low conductivity in clean air. When a methane gas sensor in the environment, the sensor's conductivity increases with the air of methane gas concentrations increase. Using a simple circuit to the conductivity change is converted to output signals corresponding to the concentration of the gas.MQ-K10 gas sensor also good at anti-interference, even put it in 2000ppm alcohol gas environment, its not influence at all, is a suitable low- cost sensors to a variety of applications.

Character:

1. Good sensitivity to methane gas

2. High anti-interference ability
