Features:
Signal output instructions;Dual signal output (analog output， and TTL level output);TTL output valid signal is low， can be connected directly to the microcontroller;0 ~ 5V analog output voltage， the higher the concentration the higher the voltage;Has a high sensitivity and good selectivity to ethanol vapor;Has a long life and reliable stability;Rapid response recovery characteristics;
Applications:
For motor vehicle drivers and other non-drinking and operating personnel on-site testing， also used in other places of ethanol vapor detection， detection of alcohol: detection range of 10 to 1000ppm
Package included:
10 X Alcohol module
