MQ-3B Semiconductor Sensor For Alcohol Gas Low Cost Andsimple Drive Circuit &etc For Industrial Alcohol Gas Alarm And Portable Alcohol Detector
Profile :
Sensitive material of MQ-3B gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol 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.
MQ-3B gas sensor has high sensitivity to alcohol gas and can resistant to the interference of gasoline, smoke and vapour. It is with low cost and suitable for various applications of detecting alcohol at different concentration.
Features:
It has good sensitivity to alcohol in wide range, and has advantages such as long lifespan, lowcost andsimple drive circuit &etc.
Main Applications:
It is widely used in domestic alcohol gas alarm, industrial alcohol gas alarm and portable alcohol detector
