Smoke Sensor

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

<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor&rsquo;s conductivity is more higher along with the gas concentration<br />
rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.</span></span></p>

<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.&nbsp;</span></span></p>
