Alcahol Ethanol sensor module for Arduino and other microcontroller projects

 
A sensitive ethanol sensor will detect levels of alcahol in the air. The level of alcohol varies the output voltage. A comparator gives a digital output. 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 first time use
Voltage : 5VDC
Current : 300mA
Sensitivity : 0.4mg/L alcohol
Size 32x21mm
