Item No.: KD0042
INQUIRY

You can easily connect it to kidsbits control board for communication using an RJ11 cable without worrying about wrong wiring and damage.

The gas-sensitive material used in this sensor is tin dioxide (SnO2), which has a low conductivity in clean air.

This simulation  gas sensor – MQ3 is suitable for detecting alcohol.  

When alcohol vapor is present in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of alcohol vapor in the air increases.

This sensor has high sensitivity and quick response.

In addition, the sensitivity can be adjusted by the blue potentiometer
