Profile
Sensitive material of MQ-2 gas sensor is SnO2, which with lower
conductivity in clean air. When the target flammable gas exist, the
sensor’s conductivity gets higher along with the gas concentration rising.
Users can convert the change of conductivity to correspond output signal
of gas concentration through a simple circuit. …
