Environmental Alcohol Sensor
This Environmental Alcohol Sensor is of the two-electrode electrochemical type, operating by the diffusion principle and as such requires no external sampling hardware. In the presence of alcohol a small direct current is produced; the sensor requires no power supply of its own but this current requires amplification to make it readable using external data collection equipment.

Please note that the correct circuit board to pair with this sensor is the version for formaldehyde sensors, 3-CBF.
