ALCOHOL 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-3 gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol gas exists, the sensor&rsquo;s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond<br />
output signal of gas concentration through a simple circuit.</span></span></p>

<p><br />
<span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>MQ-3 gas sensor has a high sensitivity to alcohol gas and can resistant to the interference of gasoline, smoke and vapour. It is with low cost and suitable for<br />
various applications of detecting alcohol at different concentration</span></span></p>
