NATURAL GAS CH4 SENSOR

<p><strong><span style=”font-size:18px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>Description</span></span></strong></p>

<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor&rsquo;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.</span></span></p>

<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>MQ-4 gas sensor has high sensitivity to methane, also has anti-interference to alcohol and other gases.&nbsp;</span></span></p>
