Description

About this item

• Sensitive material MQ-3 gas sensor is used in clean air low conductivity oxide
• When there is alcohol vapor in the environment sensor, conductivity sensor with increasing gas concentration of alcohol in the air increases
• Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal.
• High MQ-3 gas sensor sensitivity to alcohol, can resist the interference of gasoline, smoke, water vapor.
• The MQ-3 sensor can detect a variety of alcohol concentration in the atmosphere, is a low-cost sensor suitable for a variety of applications
