Winsen MQ303B Semiconductor Type Alcohol Sensor

Original price was: ₹130.00.Current price is: ₹125.00.

The sensitive material of the MQ303B gas sensor is a 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.
