10pcs MQ303B Alcohol Gas sensor

[shortdesc]Application:It has high sensitivity to alcohol and quick response and resume, widely used in portable Feature:alcohol gas detector,High sensitivity,quick response and resume[/shortdesc]Production Description:Sensitive material of MQ303B gas sensor is semiconductor material which is with lower conductivity in clean air. When the target alcohol gas exists, 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.Feature: alcohol gas detector. High sensitivity quick response and resume long lifespan low power consumption small sizes Application:It has high sensitivity to alcohol and quick response and resume, widely used in portable Technical Parameters： Model MQ303B Sensor Type Semiconductor Standard Encapsulation Metal Target Gas Alcohol gas Detection range 20~ 500ppm alcohol Standard Circuit Condition
