Alcahol Ethanol sensor module for Arduino and other microcontroler projects
This module has a sensitive ethanol sensor that will detect levels of alcahol in the air. The sensor outputs a varying voltage on the analogue pin depending on the level of ethanol and it has a comparitor to give you a digital out at when the ethanol level reaches a certain level, this can be set with the built in potentiometer.
Please note, this sensor needs to run for 24-48 hours before using it for the first time.
Voltage : 5VDC
Current : 300mA
Sensitivity : 0.4mg/L alcohol
