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;
Features
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
What's in the box?
1 X Alcohol sensor module
Resources
Analog to Digital converter not included
