Alcohol Sensor
Application:
It has high sensitivity and fast response to alcohol, and is suitable for portable alcohol detectors and automobile ignition systems, etc.Product characteristics:
high sensitivitymDescription
The gas-sensitive material used in the MQ-D3B gas sensor is a semiconductor material with low conductivity in clean air. When alcohol vapor exists in the sensor's environment, the sensor's conductivity increases with the increase in the alcohol gas concentration in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.
