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;A
