Description:

This sensor is fully compatible with ARDUI NO single-chip microcomputer, and its connection port is also compatible with Arduino sensor expansion board. The gas-sensitive material it uses is tin dioxide (Sn02) with low conductivity in clean air. When there is alcohol vapor in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of alcohol vapor in the air increases. The sensor comes with 4 positioning holes, which is convenient for you to fix the sensor to other equipment.
