Gas Sensor Module MQ-5 For Arduino

Arduino MQ5 Gas Module

Sensitive gas : Liquefied gas, natural gas
and coal gas .

Operating principle:
MQ-5 gas sensor applies SnO2 which has a lower conductivity in the clear air
as a gas-sensing material. In an atmosphere where there may be inflammable
gases, the conductivity of the gas sensor raises along with the inflammable
gas concentration increases. MQ-5 plays a high performance in detecting
butane, propane and methane, and can identify both propane and methane at
a same time. MQ-5 is highly sensitive to natural gas. It features with the ability
to detect various inflammable gases and lower cost, making it an ideal choice
of different applications of gas detection.

. Applications
This module can be applied to liquefied gas, natural gas and/or coal gas
monitoring devices for household or industrial usage.
